Barney.
It seems the Spinarak poison had still not worn off Mewtwo. Every night, he dreamt about random things he had never heard of. This night was no different.
This time, Mewtwo woke up in a clearing with some very annoying music coming from it.
Mewtwo walked in and saw Barney.
Barney: I love you, you love me...
Mewtwo: No, I don't love you. I don't even know who you are.
Barney: We're one big happy family!
Mewtwo: No... We're not.
Barney: With a great big hug, and a kiss for me and you... Won't you say you love me too...
Mewtwo: ...HELP! I'M TRAPPED IN A CLEARING WITH A HOMOSEXUAL MUTANT PURPLE CRANIDOS!
Mewtwo used psychic. Barney's head exploded. From Barney's body, mini Barneys came.
Mini Barneys: I love you, you love me...
No matter how many Mewtwo squashed, they kept coming.
Mewtwo: HELP MEEEEEE! !
Mewtwo woke up, and heard the TV from downstairs. Mewtwo walked down, and saw Mew. He then looked at the TV, and fainted.
Mew: What's wrong with my show?
TV: I love you, you love me...
END!
