Most wrestling fans have likely noticed that WWE superstars, busting their humps under hot lights, tend to perspire as they ply their trade. It's a simple fact of life. However, odds are that even the most pedantic stickler for realism never thought to himself, "Hmmm... you know what? These wrestling action figures I play with? They should also sweat." It just doesn't seem necessary. That didn't stop WWE. When business was through the roof during the Attitude Era, the company put out the "Maximum Sweat" line of figures. Hulking with disturbing musculature to accommodate the waterworks inside, these toys could be filled with fluid, then forced to "sweat" with the press of a button. Just as gross as the real thing!
