There is a
story that my mother always told me that seems most appropriate here.
My parents were at a dinner with the ministers of our church in a nice restaurant somewhere. Part-way through the meal, the senior minister decided to tell a joke:
How do you sell a duck to a deaf man?
They all thought about it for a couple seconds and then the senior minister shouted:
YOU WANNA BUY A DUCK?!
Needless to say, my mother was mortified that a minister had shouted this out in the middle of a nice restaurant. So, if you ever want to tell a joke that will make everyone in the entire restaurant stop for a minute and look at you, this is the one to tell.
