In an early scene, a character asks for Room 412. This references a famous joke from one of Stan Freberg's routines "St George and the Dragonet" which was a #1 hit record in 1953 and was a popular in-joke at one time in acting circles. The joke's punchline - the Dragnet-style cop says "I've got you on a 412 as well." What's that, shouts the criminal. "Over-acting" replies the deadpan cop.
