I've recently run (literally) into two new categories:
1. Manatee Man - large, slow man with thick leathery hide who makes "u" turns at the wall. Often diagonally so that he cuts off the incoming swimmer. Also makes mid-lane U turns with no warning to cut in front of you. These "U" turns are are mix between walking and swimming...head and body in the water, feet on the bottom. Wears headphones to drown out your grumbling.
2. Fairtale Theatre Frog
http://www.tvshowsondvd.net/...re%20_FrogPrince.gif Costume- blue long sleeve shirt, neoprene knee length knickers (also blue). Blue cap, goggles and neoprene hand paddles. Swims with the tops of her goggles above water and "paws" the water with her webbed hands. Imagine a weird, sexual catwoman crawl and you're on the right track....
I couldn't continue swimming I was choking on the chlorine from laughing so hard...
