Andy Richter Controls the Universe/Twins
From The TV IV
Twins is the second episode of the second season of Andy Richter Controls the Universe.
Byron has a badly burned back, and his bandages, where he can't reach them, require frequent changing. A nurse is too expensive, so Wendy volunteers to let him stay with her. Keith decides to stay over as well, to share the responsibilities. They immediately fall into typical parent/child roles, with Wendy handling most of the changing, and Keith drinking more and coming up with excuses to not go home.
Jessica was just dumped by her boyfriend, the latest in a string of relationships gone awry, and Andy blames her choice in men. After meeting an attractive and intelligent man, Ben (Dan Cortese), Andy decides to play matchmaker. Things go really well, but Jessica notices that his conversational skills and performance in bed vary greatly from date to date. When Andy learns that Ben has an identical twin brother, he suspects them of sharing Jessica by alternating dates.
