The reason I am so pissed is that I work in a company where we do things and make jokes that would get you kicked out the door in most suit companies and everybody enjoys it -- including the girls (who are often the best) -- and yes there is the guy who doesn't find it funny to change his screen, so we don't. To him. If he finds it obnoxious that we make those jokes with others, he can deal with it or leave.
And yet, if somebody where to join us who would get annoyed working there do you suggest the rest of us should leave?
I wouldn't make the joke I did in a company that didn't appreciate it but I wouldn't stand for it being change just to fit a few people either.
Since everyone in your company enjoys this attitude, it's nothing but good, clean fun (or good dirty fun, depending on the color of the joke).
But someday you may hire someone who, as it turns out, does not appreciate the jokes. Or perhaps, like Jessamyn, enjoys the jokes sometimes but feels that they are overdone to the point of being irritating.
I would not advice you to tell this person "If [you] find it obnoxious [... you can] deal with it or leave." Because in the US (I can't speak for other places) that is illegal. If this sort of behavior is pervasive it is said to "create a hostile (or offensive) work environment", and if someone is fired (or effectively forced to leave) because they do not enjoy the behavior then they are well within their rights to sue your company.
This seems to be a reiteration of the same point: you believe that if somebody finds the work environment hostile, it's ok to pressure them to leave. You're really not seeing anything wrong with that?
I'd also question your belief that "the girls" (who are, I take it, 8-12 years old) are ok with it. Go talk to some people in the field who have had a few jobs but aren't stereotypical. E.g., gay, female, or black. Ask them if they've ever laughed at something that made them uncomfortable because they wanted to fit in and felt unsafe doing anything else. Because you're ok with pushing out somebody if they don't like the joke, guess what: if they don't like the joke, they'll still pretend to you that they do.
Given that you've said you would try to force someone who didn't agree with you out of the company, I'm sure all your current coworkers are completely honest with you about what they enjoy.
"Hostile work environment" is a set of landmines in every US employer's terrain. If you locate here, you can't legally or practically avoid employees who take this stuff very seriously (though I've been fortunate in not seeing anyone go ballistic over anything). The only workable response is to suck it up, don't commit thoughtcrime in the office, and go have a drink and unwind with the people whose discretion you respect.
