Yeah see I don't like the foul mouthed stuff. Red Skelton and Lucille Ball were able to get the humor across without being foul about it.
Robin Williams would tailor his act to his audience. If it was an early show and minors night be present he was pretty tame. Adults only it was fair game.
I went to a 6pm show for Tim Allen and man was it ever foul, even with kids in the audience. Bad enough that I actually got up and left.
