Numb Butt Wheelchair Club

Alright, listen up, nimrod. This "joke" is about a wheelchair club. Wheelchairs are for people who can't walk, sometimes 'cause they can't feel their legs or butt. The joke is that the club is called "Numb Butt Wheelchair Club," meaning everyone in it probably can't feel their butts. The punchline is that having no feeling is "no problem," which is ironic because, well, it kinda IS a problem if you can't feel your own butt. And you probably have a similar problem if you think this is high-brow comedy.
