"Hold it right there, crackerjack. Before you grab your crotch and spin like a whirlin' dervish, you gotta learn how to skate with safety! And just how can you learn? Don't worry, we've brought in the master of safety ... Meet Tom. He's the Executive Director of the Pro/Am Skateboard Racing Association."
From I-Mockery comes this skateboard safety film, circa 1975, which details all the horrible things that can happen if you're not wearing your special skating equipment (we especially like the heavy asbestos gloves). And beware of speed wobble!
The video in its entirety is here, but I-Mockery's description of it is funnier.
