Waylon Smithers is Mr. Burns' sychophant assistant on The Simpsons.  Smithers is definitely portrayed as a closeted homosexual having frequented Springfield's gay village and going on vacations to an all male resort.  He also seems to have creepy fantasies about Mr. Burns.

Waylon has basically grown up at the nuclear power plant when his father died of radiation poisoning there.
