In "Throw Mama From the Train" where Billy Crystal is haning from a rooftop (or something, I forget), and Danny DeVito asks Crystal what he's doing, he says "I'm selling the Watchtower. What do you think I am doing?"
Saturday Night Live: LANDSHARK! Chevy Chase beats up a JW thinking its the landshark at the door selling the watchtower.
and i know it's probably not a JW reference, but an old Saturday Night Life skit where the Bethel basketball team beats a bunch of Knights of columbus basketball teams is ironically good. Bethel (I assume it aint JW Bethel, but who knows), sends over a very cocky spokesman to accept a trophy from the Knights at the Christmas dinner. In the end they all try to sing christmas songs, but only the Bethel guy knows all the words. Has anyone else seen this bizarre skit?
