Whats your favorite bad joke?

I love to make really bad similes/metaphors like "I have the memory of a fish with very poor memory" or "I'm as tall as a tree thats my height".

A blonde walks into a bar and asks for a double entendre.

So the barman gave it to her.

Both work, but I’ve always heard it as “So the barman gave her one.”

Maybe mine is the British version idk
