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.
Mr. Burns: Oh, and one more thing: you must find the jade monkey before the next full moon.
Smithers Actually sir, we found the jade monkey. It was in your glove compartment.
Mr. Burns: And the road maps, and ice scraper?
Smithers: They were in there too, sir.
Mr. Burns: Excellent! It's all falling into place...
Smithers: People like dogs, Mr. Burns.
Burns: Nonsense, dogs are idiots. Think about it Smithers, if I came into your room and started sniffing at your crotch and slobbering all over your face, what would you say?
Smithers: Umm...if you did it, sir?
