Some people severely overdo the jokes to the point where it's no longer funny anymore. It's the same with sarcasm and other forms of wit. People think they can just throw idioms around because they see it on tv but in reality they have no sense of style or restraint. Sarcasm is supposed to be like salt - sprinkle just a little every now and then to add flavor. But if you add to much you only taste the salt. Who wants to eat salt?

You either put your foot down and get them to lay off or you make new friends. All this "Big Bang Theory" is making people annoying...

I don't think it's a bad show but people try too hard to emulate it when it's a dramatization.
