What should we do with people who don't have a sense of humour?

Well, you can't really do much about them. That is part of their personality. I'm sure they have a sense of humor to some extent, maybe it's just a different type. But yeah, you can't really make them suddenly have a sense of humor. I think the best thing to do is to either deal with them, or don't joke around with them if you know they're not going to get it.

There are alot of people out there that tend to do that with any joke and i always remind them that it was only a joke and to lighten up a bit.

I think we need make joke of him :)
