le'sigh, i figured the baby jokes wouldn't fly. props on the pilot joke, themocaw, i've heard that one before and it's a great one.
unfortunately most of my jokes are offensive to some group or just so totally vulgar that i shouldn't put them in here.
Wikipedia "No Soap Radio."
one of my sociology profs pulled off an elaborate no soap radio joke in a lecture. he had the TAs tell half of their discussion sections (half the students) about the set up, so all the TAs and half of the 200ish person lecture lagued at "no soap, radio!"
unfortunately it didn't work quite as well as he'd have liked. out of the other half of the class, only a fraction of them were actually paying attention.
