The Happy Ear Wig Motel is a motel in Springfield.
Homer and Marge hire the Conformco Worker to brainwash Bart into returning home. The worker takes him to the motel and starts the treatment throughout the night. This briefly interrupts Joe Quimby from cheating on his wife. This is probably one of the many places he uses to have affairs. Once the treatment is done, it is revealed that instead of Bart, he accidentally brainwashed Hans Moleman.
