It was a Thursday and it was pizza-night. All of them were in Sheldon's and Leonard's apartment except for Amy, who was in a neurobiology conference at Washington. She was on Skype with Sheldon altough they weren't in a relationship now after they both agreed on terminating their relationship agreement. They were still friends and Amy stayed with their group not just because of Sheldon but because of her bestie, Penny as well. Recently she started dating with one her colleagues.

„Sheldon, why don't you just sit down with us and eat your pizza?" Leonard asked him.

„I can't leave Amy. We're discussing her section tomorrow. She wants to start it with a joke but she can't figure out any so I help her." Sheldon answered.

„It is a case of blind leading the blind." Howard murmured and for that Bernadette punched him. „Ouch. It's just the truth, Bernie, and you know as well as me."

Bernadette smiled at Sheldon. „Why don't you just take your laptop on the table so we all can speak with Amy and perhaps together we can find out a proper joke."

Sheldon took his laptop on the table and they all greeted Amy.

„Hey Amy" Howard started. „I always wondered, why did you drop out Sheldon?

„She didn't drop me out, Howard." Sheldon refined. „We agreed that we terminated our relationship agreement due to the fact that Amy cannot overcome her feminime urges."

„Sheldon, you can barely hold my hands!" Amy yelled. „Yes, I admit that I am a woman and thank God I have a healthy body and I have feminime urges and I want them being stufficed. And I'm happy to say that finally I've found someone who can tolerate and satisfy these urges."

„I'm satisfied seeing you in a happy relationship, Amy" Sheldon said.

„Sarcasm?" Penny asked doubtly. She was sitting in the couch between Sheldon and Raj.

„No." Sheldon said astoundly. „I am indeed pleased with Amy's current state. Now I don't have to hear her suggestions about how we could modify some terms in our relationship agreement."

„Then why did you hate it when Stuart asked Amy out for a date?" Leonard asked.

„Don't be ridiculous, Leonard." Sheldon said. „That relationship was repellent. Contrary to Stuart, Frank Hudson is a notable neurobiologist who won the Internationat Eppendorf and Science Award in 2009."

„Ok, that's enough of me." Amy said. „I want to hear some news from you. So what's up, buddies?"

„It seems that Sheldon will get a competion." Leonard started. „I'm sure you know who is Marc Stapeton."

„Of course I do. He wrote the bestseller book 'Looking into a beautiful mind' about recent theoretical physics especially string theory. He has another point of view than Sheldon."

„Another point of view?" Sheldon yelled. „He has the exact opposite theory than me. Of course he isn't right but damn it I can't prove it yet."

„Oh, is he that Marc Stapeton who was in Late Show with David Letterman last Tuesday?" Penny asked excitedly. „He was so smart and he was cute and he was so... hot."

Sheldon turned to Penny furiously. „If you say another word of that man that will be a strike and you already have two!" Penny chuckled but she stayed in silence.

„Anyway, Amy, our university invited him to the next term to teach about his theory" Leonard continued.

„Why didn't they ask Sheldon to teach about his string theory?" Amy asked.

„They asked me." Sheldon answered furiously. „But because I refused to teach labradoodles, they invited this self-conscious, swollen-headed dummy who made dreadful from theoretical physics."

„The pot calling the kettle back" Howard murmured again. The others chuckled except Sheldon.

„Why must you say idioms after every sentence I say?" Sheldon asked while raising his eyebrows. „Oh, do you know that John Saeed defines an "idiom" as words collocated that became affixed to each other until metamorphosing into a fossilised term." He nodded and smiled with his all-knowing smile.

The other just sighed. It was typical from their genius but sometimes irritating friend.

„And the university is going to hold a ball to his arrival next Saturday" Leonard finished his announcement.

„Oh, then I'm afraid I will miss this sensational event" Amy answered. „Frank asked me to join him in his next conference to New York. We're going to travel next Thursday."

„Amy" Sheldon yelled. He looked sulky. „You promised me that despite our romantic relationship is over you will be my partner every time when the protocol desires. This is the event where I can't go without a partner professor Siebert has strong opinion on this."

„I'm sorry, Sheldon" Amy said, „but now Frank is more important to me. I am going to accompany my current boyfriend to New York."

„And with who I will go to the ball?" Sheldon asked cluelessly. „Leonard has already asked Leslie Winkle, Howard has Bernadette and Raj has found someone in an online dating site who accepted his offer."

Penny turned to Leonard asking him „Why did you ask Leslie instead of me? Just because it didn't work out with me, I would willingly go with you to a ball where I could meet Marc Stapeton."

„Uh, Penny" Leonard raised his eyebrow in a strange way like he always did when he was embarrased. „Uh, actually, it was Leslie who asked me out and I didn't want to loose my chance so uh, I said yes."

Raj whispered something into Wolowitz's ear. They both chuckled. Leonard put down his meal. „What is so funny?"

„Raj said that you chose Leslie because you had better chance on her than Penny to finish the evening with firework."

At the same time Penny punched Raj while Bernadette punched Howard.

„May I remark the fact that when somebody is asked out by Leslie they usually end in having coitus?" Sheldon chuckled in his own way. „By the way, this doesn't solve my problem that I don't have anybody to the ball."

„Why don't you ask Penny?" Amy proposed. „She has the glamour, the beautiful long blond hair, the perfect shape for a prom dress. I am already jealous on you that you all can see her in that ball!"

Sheldon thought about the idea for a moment. „Interesting. She's attractive, she can behave in big crowd and I don't have to afraid that she want physical contact with me." Penny grimaced at the sentence. Sheldon just couldn't say a compliment without an offend in it.

„So, I assume that Penny can go with me." Sheldon finished.

„Why would I go with you?" Penny asked.

„Listen, bestie" Amy said. „You can wear a wonderful dress Sheldon will buy, you can make your hair, you can have a free diner, you can dance and you can meet Marc Stapeton. And if it's not enough you can wear heels beacuse Sheldon is taller than you."

Penny smiled. „Yeah, that's the only thing Sheldon is better than Leonard." Leonard smirked. „OK Sheldon I think I can accept your nice invitation."

„Wait. You really want to go with Sheldon?" Leonard asked.

„Why not?" Penny answered. „You will go with Leslie and maybe you'll have sex. One thing I'm sure I won't have sex with Sheldon. So I don't see why it is a problem with you if I go with him."

„Okay, have fun with each other." Leonard said.

„Anyway, I won't buy a dress for you." Sheldon said to Penny. „You have too many clothes in your wardrobe, you can pick one of them."

Penny just stared at Sheldon. She thought maybe she made the wrong decision when she agreed on going to that ball at the university. But then she thought about her dress – of course she knew what she wanted to wear – and the high-heeled shoes she was going to wear – thank God that Sheldon's so tall – and that she could meet that hot science man. Maybe she could enjoy herself.
