Theme: This week's prompts were taken from submissions to the website My Life is Average.
Prompt: McCoy, Joanna - Today my 2yr old daughter said her first knock knock joke. She said "knock knock" I said "who's there?" she said "me"

Knock, Knock

″What are you doing now, sweetheart?″ Leonard called as he began rinsing the soap bubbles from his hair. He'd been desperate for a shower after his long shift but had no one to keep an eye on Joanna while he washed so he'd set her up outside the door with a pile of picture books and left the door open a crack so they could talk while he showered.

He'd questioned her about her day, asked her to ″read″ the books out loud to him, and sang songs with her to both maintain her attention and keep tabs on her whereabouts in his small on-campus apartment. He'd gone on a childproofing spree when Jocelyn had finally agreed to let Joanna visit him for a few days but wasn't completely confidant in his ability to keep ahead of his inquisitive daughter. And Lord knows Jocelyn would never allow him to see Joanna ever again if something went wrong on this visit.

″I'm picking out a new book, Daddy!″ Joanna's high voice was filled with happiness as she answered him.

″Which one is next?″ Leonard soaped up quickly, determined to finish the task as soon as possible so he could spend the rest of his evening cuddling and reading with Joanna.

″The one with the doggie.″

″Oh, okay. Why don't you tell me about it.″ Leonard didn't remember buying her a book with a dog in it, but she sounded excited about it, so what did it matter? He began rinsing off, listening for her reply. For a moment he thought he heard a swishing sound over the rush of water pouring around him, but he knew he'd locked the door when they'd arrived home that evening after picking Joanna up at the shuttle station and Joanna was right outside the door, right? ″Joanna?″

For several seconds there was only silence, then, just as he began to get nervous, he finally heard, ″Daddy?″ Her voice came from right outside the door and Leonard breathed a sigh of relief as he shut off the water and grabbed his towel, drying off quickly and generally ineffectively before slinging the towel around his hips.

″Be right out, darlin'.″

″Hey, Daddy! I learned a new joke today, wanna hear it?″

″Sure sweetie, tell me.″ Leonard had no idea what kinds of jokes a two-and-a-half year old might come up with, but he'd go along with it. He grabbed up a comb and ran it through his hair and decided to pass on shaving again – he wasn't all that bristly.

″Knock, knock.″ She punctuated her question by knocking on the bathroom door.

″Who's there?″ Leonard reached for the door, waiting for her punchline.

″Me!″ Joanna shrieked the answer with delight in her voice and broke down giggling madly. Leonard pushed open the door swiftly and snatched his waiting daughter up, and tickled her, causing her shrieks to escalate. She tried to say something but she couldn't hear her over her giggles.

″What was that, sweetpea?″

Joanna took a deep breath, still shaking with laughter. ″And Jim!″

Leonard froze. ″What?″

″Me and Jim. Are there.″

Leonard heard a snort from the corner of the room near the door and turned to find his best friend red-faced with laughter. This was also about the time that he realized he was still clad only in a towel, slung low around his hips, and that both his arms busy holding up a squirmy Joanna, leaving no free hands to secure the towel's precarious perch. Well, shit.

He never should have given Jim the code to his apartment.
