Boss hires a woman- thinks women should be FOH (Front of the house). Woman sucks at it and wants to be BOH - where she shines. He keeps putting her in the FOH until she quits.

Guy says he wants to be an actor in a play. Director says no: Puts him on stage lighting where he's miserable and does horrible on. Director states he needs to try harder. Guy quits the play.

Boss hires Tom &Jerry. Tom sucks as a boss. Tom's metrics are horrible and most of his staff can't stand him. Jerry on the other hand metrics are great and his staff likes him. Boss decides to move Jerry's Team to Tom and their metrics plummet.
