Big Bang Theory Quote
Sheldon: As a male I have an evolutionary drive to perpetuate my DNA, and restricting myself to a single partner is against my nature.
Amy: We sleep together once a year; you want other partners?
Sheldon: Don't blame me; blame your pal Biology. He's the pervert pulling the strings here.
Amy: You want to see other people? Go see other people.
Penny: Hope one of those people is a monkey, 'cause this is bananas.
