Here's a place to share your favorite gems from Seinfeld. Here's one of many great quotes from my favorite episode (and the source of my current signature):
"Hey, George, the ocean just called. They're running out of shrimp!"
"Oh yeah? Well the jerk store just called. They're running out of you!"
"Well, I don't see that it would matter. You're their all-time biggest seller!"
"Uh, uh, well, I slept with your wife!"
"George, his wife's in a coma."
