How did they achieve Sam's slide-a-beer-around-the-corner trick? Was there a track, or was that something Ted Danson could actually do? Or was it some third things?
This is referring to the “Endless Slumper” episode of CHEERS from season one, written by Sam Simon and directed by James Burrow. I’ve included the video of the show. Well worth watching the whole thing.
Anyway, here’s how Jimmy and his crack crew did it:
A thin clear plastic filament was attached from the corner of the bar to the handle of the mug. Ted slid the mug. As it reached the elbow the filament tugged at the handle and swung it around the counter. Needless to say, the studio audience went nuts. Physics -- a comedy writer's best friend.
