Once, as we were walking out of a local bar, my friend programmed "Loving You" by Minnie Riperton on 8 times in a row on the jukebox. The next time we came back, that song was no longer on the jukebox.
I used to do something similar when non-regular idiots would try and take over the digital juke box at a regual watering hole of mine, and they would pay extra to skip their songs to the front of the cue. I did it a bit more subtly and play full versions of Alice's Restaurant and In-A-Gadda-Da-Vida. That would usually clear the place.
