The best thing to do when the seadonkeys are around is to drop a silent but deadly when you walk by them. They are usually so fat, they don't know if it was them or not. Then they wonder if everyone is looking at them because they are a whale, or because they reek. This tends to reduce their motivation to come to the gym and "hog" up the equipment. Works almost everytime. The only exception is when you are trailing - and the nasty fart follows you across the gym - if that happens - you have to head straight for the lockeroom, or else you will be busted.
