S03E07 : The Guitarist Amplification
Leonard : What am I supposed to say? "Sure Penny, I'm cool with your old boyfriend sleeping in your apartment"
Leonard : *imitates Penny's voice* ""Well Leonard, it doesn't matter if you're cool or not cos I'm Penny, and I'm pretty, and I could do whatever the hell I want!!"
Leonard : "Oh I get it, you think you're doing me a favor just by being in a relationship with me?"
Leonard : *imitates Penny's voice* "No no, Leonard...I'm doing you a favor just by being in the same room as you!"
Sheldon : LEONARD STOP THE CAR!
Leonard : What?
Sheldon : I can't listen to the two of you fight anymore!!!
