Why are they showing old episodes?

In Seinfeld's case it is a bad ploy however for it serves to remind us of how good the show used to be and how bad it is now.

Actually, it's just business. Nielsen does "sweeps" during certain times of the year--November, February, May and July. So, you should expect new programs at the beginning of the season (September), and in November, February and May. The best reruns should be in July.

Kramer opening a pizzeria reminds me of something. Wasn't he talking to someone once (Elaine I think) about opening a do-it-yourself style pizzeria or something? It's a very vague memory, but he was very excited about the do-it-yourself part. Does anyone remember this?

Certainly. This was one of Kramer's big business ideas that also included the likes of a do-it-yourself yogurt bar.
