I strongly disagree with this comment as well.
First off, "Degrating" isn't a word. "Degrading" is. And if you're offended by this joke, then maybe you have issues with yourself. Maybe it hit too close to home?
If you're a guy that can't laugh at jokes that make fun of men, then you need to "be a man" and grow some thicker skin.
Erectile Dysfunction commercials are like Feminine Hygiene commercials. They make people a little uncomfortable, but are a necessity. Sure, the joke is similar to an ED commercial, but so what?
Commercials make you remember a product in one way or another. This happens to be remembered through a joke.
