The most PG (STEM) person I know in real life isn't witty at all. When he is drunk, he tries to be funny but more often than not, his attempts just end up making him look like a sexist jerk, which is sad because he is a genuinely nice and caring person.

My SO - a former prodigy for what it is worth - thinks he is witty but he too is more offensive than he is funny.

They both think something is wrong with my sense of humor.
