Another Sherlock Holmes reference occurs at the start of the scene in the tobacco shoppe where he will purchase his new cane: House tries out a curved styled pipe which resembles a calabash pipe. The calabash pipe, magnifying glass, and deerstalker hat are accouterments that the famed detective uses in the cinema and theatrical versions of his adventures and which are used on occasion as stunt props in House M.D.
House: It's a little too "Marilyn Manson in the retirement home". House is referring to a musician and artist known for his outrageous stage persona and image as the lead singer of the band that bears the same name. In many of his music videos and concerts Marilyn Manson is seen with a cane that has a skull-formed handle.
