When someone tells a bad joke, do you feel sorry for them and try to laugh?

We ask at the end of the joke if we were supposed to really laugh. One friend of mine is kind of expert in telling stupid/bad jokes. So even if the joke is not funny we laugh..at him.

I'm really evil. I do a fake laugh so it's obvious it wasn't funny. lol

I laugh when I don't get the joke also. lol 😅
