Oh god. My dad used to sell these things. I still laugh when I think about the summer I spent answering phones at his office. It's actually not true that Pos-T-Vac was the only one covered by Medicare.
Sadly, this isn't even the funny one. The funny video has an old guy with a shit-eating grin sitting next to a naked younger guy in a robe who was filmed from the neck down. Mr. Shit-eating Grin seemed overjoyed at describing the benefits of the Pos-T-Vac while the Headless Man was grunting and demonstrating it. The thing about these "medical" penis pumps is that you're supposed to stretch a rubber cock-ring around the rim and then snap it off to keep the pumped member tumescent. In the video, when the Headless Man demonstrates this, he winces in his seat from the sting of it.
Incidentally, if you drill a couple of holes into these things they make an excellent steam-roller. The seal is air-tight and the hand-pump makes it easy to get hits where you suck in an entire bowl's worth of smoke. But believe me, you do not want to answer phone calls from customers about their penis pumps when you are that baked.
