Why don't people have more sense of humor?

I made a couple friends and relatives believe that my ex boyfriend followed me and just beat me up (by applying some make-up) for a few minutes. Even after I've repeatedly told them all it's just a joke, no one was laughing. Once in a while, I just like being creative with pranks or lighten the mood even if it's a bit dark.

Seriously I haven't even spoken with my ex boyfriend for 2 years now and last thing I heard he's with someone else. We just went our separate ways, unfriended each other and that was it.

Where is the sense of humor? I've seen others play pranks similar to this and they have their followers that find it creative.
