Given that there are not too many full-time tag teams around at the moment here are a couple of "fantasy" ideas for your ponderance.First, a "Men in Black" team gimmick, with our team on a quest to rid the WWE of all the alien scum currently posing as wrestlers. This is a team that could be neither face or heel, have a bit of comedy value and could, say, be Agents Venus and Saturn?Second, a "Statler and Waldorf" gimmick. This could be two guys in a production booth doing alternate voice-overs for other wrestlers promos/matches, again with great comedy value. Then getting found out and challenged, etc. This would also provide the WWE with a chance to poke fun at itself, bringing probably the best part of The Muppet Show to Raw/Smackdown. Thats a couple of ideas... any more?
Because there was significant plot progression. Piper in WCW was a big deal around this time period and was legitimately entertaining in a lot of ways. The nWo winning the tag titles was also a pretty big deal.
