5) Inflatable groupie

Rock history: There is only one good reason to join a band, and that’s to get laid. Frequently.  

How it works: Since Rock Band isn’t likely to get you any actual groupies, you’ll be able to hit up the inflatable groupie whenever the mood strikes you. Self-inflates and self-fellates with USB-powered pump.
