Me llamo Earl: Monkeys Take a Bath

SINOPSIS

When they were kids, Earl and Randy once saw their rather sensitive neighbor Clark Clark cry and decided to play tricks on him (like giving him a newspaper stating the suicide rate under babies has increased) just to see him cry again. Not much later, he and his wife moved. Now, Earl wants to make up for this and he visits Clark Clark to apologize and ask him what he can do to cross him off the list. Clark then tells Earl the reason he moved wasn't the pranks, it was because he had sex with Earl's mother! Shocked, Earl goes to his parent's house and confronts his mum. When his dad finds out, he moves in with Earl and sets out for revenge by having a one-night-stand as well.
