I live in the St. Louis Burbs, my team names have been:
The Eastern MO Rons
St. Louis Archers
Swamp Ass is the feeling you get in mid July, when you're working outside in the humidity, and your butt is so sweaty that if feels like you've got a swamp going on. Not much to do with baseball, but it does inspire greatness.
For the Archers, I used a picture of Scott Bakula for the team logo, got some laughs.
Had to abandon the Eastern MO Rons, too many dumbasses didn't get it.
