Think you know everything there is to know about 'Seinfeld'? Ok, maybe you do, but for the rest of us, TV Guide Channel put together a special called '25 Things You Didn't Know About ... Seinfeld.'

For example, Elaine isn't the only one who can work for J. Peterman. In fact, J. Peterman is a real person with a real catalog that 'Seinfeld' just happened to make famous. And John O'Hurley, who played J. Peterman on the show, actually bought the company a year after Seinfeld ended, bringing it out of bankruptcy to co-own it with J. Peterman himself.

A lot of words and phrases from Seinfeld have made it into our everyday language. Yada yada yada, not that there's anything wrong with it, close talker, hipster doofus, to name just a few.

TBS has a contest at their site. They've created a poster that includes 38 references to the show. Can you find them all? The answers are available at a link just below the poster. Some of them are hard to figure out, but you can enlarge the poster.

I'm having a hard time picturing John O'Hurley as a dad. Specifically, as the father of a baby. I'm sure he'll be a spectacular parent and all, but his booming voice and rigid stature must be alarming to an infant. Luckily, the kid will simply know him as 'dad', rather than J. Peterman or champ of Dancing with the Stars.

Anyway, O'Hurley and his wife, Lisa, announced the happy news yesterday. No word on a due date for the baby O'Hurley.
