Jazz musicians, and big band players before them, were semi-notorious for incorporating a couple of bars of totally unrelated, well-known pieces into a song they were playing. Sometimes, it was for comic effect and at other times, just to demonstrate their musical dexterity. The most flagrant example of the former can be demonstrated by a song like "The Sheik of Araby," wherein each line is followed by the tag, "with no pants on." I saw a bunch of union musicians pull something like that at my high school prom. I think the only person among the faculty who "got it" was the band director.
