My oldest existing team (1988 to present) is Hairy Fishnuts.
16 years...nine championships, four 2nds, once thrid, once fourth, once seventh.
Some of the other teams I have also run include the following... since 1984:
Midgaard Purple Ogres,
Pinnacle Mt. Oysters,
High Flop Pies,
Hollywood Love Doctors,
Dr. Terror's Team of Horrors,
Ain't Worth Spit, and
My .02 because I sure have fun shaping the personality of the team to its given name. Some come from somewhere (e.g. Hollywood, Midgaard)
But many just exist with arbitrary names.
Cannot stand for guys in my leagues to call themselves So & So Braves, So & So Cubs, and Whatever Mets. Or Nameless, Undecided, etc. ALL these type of names imply to me a player that hadn't even given thought enough to give the team a decent/ funny/ cute name. And lazy players....well, I just kick them around like they deserve.
Another thing I noticed over the years is that guys that give disparaging names to their teams don't hardly ever do well in the standings. Perhaps, because they expect so little of them and then they get what they expect. HAR HAR!
