I Love You

Watching Seinfeld...George contemplates whether to say "I love you" to a girl he really likes. (he really likes her because she shows an interest in his inane theory that toilet paper hasn't changed in his lifetime).

Jerry and Elaine express concern about the move, since George thinks he's only got about a 50-50 chance of a return, "I love you," return. George is frustrated because he's never gotten to say "I love you."

"You've never said it?"

"Once. To a dog."

Why do I laugh out loud when watching that?
