The following joke is from a comedian, whose name escapes me (or I'd give him credit):
A captain gets on the intercom and gives the standard cruise announcement. He thinks he turned off the intercom but forgot. He proceeds to tell the FO "well, I think I'll go take a s-- then f--- the stewardess." This goes over the intercom to the cabin. A stewardess starts running up the aisle to tell the captain to turn off the intercom, but trips and falls at the feet of an old lady. As the the stewardess is getting up the old lady says to her "there's no sense in running, honey-you heard him say he was going to take a s--- first."
