Some jazz musicians of earlier generations were noted practical jokers   - many documented in the excellent book JAZZ ANECDOTES by
Bill Crow (recently re-printed) and also JAZZ SCORE (mislaid my copy and forget author).
Chief rascal was the great jazz violinist Joe Venuti. A favourite prank of mine is the following:-

Venuti looked through the local musicians' directory and rang up all the bass players (some versions say double-bassists others tuba players, but whatever). He told each one he had a gig for them and if they waited at a certain spot at 8pm on Saturday, they would be picked up. He had a friend with an apartment overlooking the pick-up point, and peeked through the curtains as the increasing number of bemused musicians gathered one-by-one.
The Union found out and fined him, but he thought it well worth it.
Later, at one of his gigs in Chicago, 26 bass-players turned up in a good-natured pay-back. But it cost him a hundred dollars in drinks for them.

On another occasion, Venuti was on a vaudeville bill with Roy Rogers   The cowboy star always made a grand entrance astride his horse Trigger. While they were waiting in the wings for their cue, Venuti discreetly tickled the horse's genitals with his violin bow.
Finally making their entrance, Trigger, of course, sported an impressive erection, bringing rapturous applause from a delighted audience.
