Sounds like this is from the Jealous School of Humor. Or, perhaps a better title would be the Sour Grapes School of Humor (Same difference, I'm just partial to foxes.) And I have a feeling that "Hey, it was just a joke..." is going to be put into play here as well.

In other words...jerks.

I don't think you're overreacting at all. And I hope the people in question either shut up and leave you alone or get a clue.

Both would be good.:)
