Seinfeld Easter Egg - Seinfeld on Seinfeld

This egg occurs in the episode "The Blood." Elaine and George are at Elaine's friend's house outside of the city, where Elaine is babysitting her friend's son, and is trying to get out of it because the kid keeps pouring juice in her purse and being a pain. When George starts talking to Elaine's friend in the kitchen, they start to discuss the "erotic qualities of the salted, cured meats." They both go down to the floor, and then the woman turns on the TV. If you look closely, "Seinfeld" is on the TV. It is a scene from Jerry's apartment. It's only there for a split second though.
