"If you don't have a sense of humor, don't try to be funny."
If you just want to be good at conversation and social stuff, get a copy of "How to Win Friends and Influence People" https://en.wikipedia.org/wiki/How_to_Win_Friends_and_Influen...
It's cheesy but it works.
That said, if you are really after being funny, then know that the essense of comedy is timing. Being funny is more like dancing than acting, say. Good news is it's a skill and unless you're hopeless you can practice and learn it. Get yourself a copy of Ol' Asimov's "Treasury of Humor" and just tell people jokes and practice your timing and delivery. Good luck! It's wonderful to make people laugh!
