Yes explaining a joke makes it less funny. I didn’t say it was a funny joke. But I did say that because you are misunderstanding how this joke isn’t relying on a joke being known before hand or sounds because of some meta joke commentary. At some point a joke has to be based on something. Whether it’s a misunderstanding or not.

Jokes are only truly funny when told in your native language. Even then, only somewhat smart people get them. Not Rhodes Scholar smart, but more with it then the average bear.
