You know that "Seinfeld" episode where Jerry and George pitch their idea about "nothing" to the NBC execs? (And if you don't, please don't tell me. I like you just the way you are, and if I learn of your lack of "Seinfeld" trivia, it might come between us.)
On the episode the NBC exec. introduces his daughter to Jerry and George, and Jerry asks, "How old is your daughter?" The NBC exec. replies, "15." George says, "That's a fun age." Jerry looks at George like he has two heads, and everyone across the wold laughs hysterically.
I think about that line all the time.
