Dharma: (about Greg's ex-girlfriend) She's perfect for you.
Greg: Fine. Dharma, it doesn't matter if there's somebody out there who, on paper, is perfect for me, because I love you.
Dharma: Yeah, well, a dog can love a chicken. But eventually he's gonna want another dog, 'cause chickens don't chase cars, and all the love in the world won't change that.
