I used to do standup comedy and I had a bit about seeing a deaf girl looking at dildos in a sex shop. The idea of the joke was the racket she would make during sex, and that you could never tie her up because you couldn’t talk to her. I would say dirty things in a muted voice like a deaf person has, its kind of mean but people would really laugh hard at that joke.
I had another one about peeing with a boner that was a crown favorite, but that one was pure physical comedy.
