At first, this looks like an attempt to build a sitcom joke by giving dicks little legs to walk around on, rendering the rest of the man obsolete. But then you notice that the little feet are locked together, your brain reorients the picture and you immediately buckle over in pain.
Patent # US 7,828,718 B2
That's not an exercise machine, that's a spring-loaded genital noose. That is the wrong kind of well hung. In fact, you're being hung and drawn -- that's two-thirds of all the worst things even medieval psychopaths could do to the human body. Marsellus Wallace would approve. We should only be grateful the inventor didn't hear about quartering or he'd be advertising a pair of crossed blades to give you 400 percent more dick.
The patent claims to expand "without pain while holding a glans side of the penis," which is the most agonizing contradiction I've ever read. He states that the machine cannot be detached easily, as if that's a good thing, proving that he's been sent from a mirror universe to prevent regular Earthmen from breeding. The patent boasts that this can be used "even by a beginner for a long time with small pain," though describing their problem as a "small pain" is literally a dick thing to say to an amateur c**k expander. The craziest bit? This isn't just a patent, it's a real product.
