I forgot my preemptive strike

... dudes at the gym who weigh themselves.
Wait, I'm not done. It's a gym. You got out of the sauna. I've weighed myself plenty of times after about ten minutes in the sauna, hoping the heat melts off an extra ten pounds.

This preemptive strike goes to the guys who are about ready to step on the scale, then go back to their lockers ... and remove their underwear.
Sorry, mate. But unless you're wearing some decent chainmail, that underwear MAYBE puts a few ounces on the scale. That five pounds that you're hoping will come off if you remove those Hanes ... isn't going to happen. Try drying your hair. AH! - still won't happen.
