Not sure if this has been done, but honestly, I ain't going to browse through numerous pages about any topics about Seinfeld episodes they should have. Basically, since going off the air, things have changed greatly since the Internet became ever so popular. Anyway, I doubt they are going to make something actually new, since most have probably changed since the past few years. Still, I would like to actually see a episode that would have something to do with the following things:
Cell phones: Possibly Texting, ring tones, trying to find service. Could see Elaine doing something that would annoy people with her own.
Online gaming: Now this I can see Kramer doing, considering his character. MMORPG with him getting little rest.
Web site: Perhaps George creating a website and trying to get hits.
Ebay: Jerry i could see trying to buy something on it. Maybe Kramer. Possibly George. Not sure about Elaine.
Really can't think of more, but I will take any suggestions if any-ones willing to reply to this.
