From TJo:
Guy with a 70-word vocabulary doodles on sleeping Naked Chick in a fit of sheer immaturity, Naked Chick wakes up and attacks Guy, Guy accidentally marries Naked Chick, and then the two gang up with Noisy Girl while trying to avoid Perverted Villain and his moronic minions. Meanwhile, Perverted Villain's fiancée, Naïve Princess, disobeys her father's word and goes off in search for her love.
Got all that, or should I run it by you again?
