Waylon Smithers, Jr. is a gay character from The Simpsons.
He is the assistant of Mr. Burns, the boss at Springfield Nuclear Power Plant. He remained closeted about his homosexuality for years.
The idea for Smithers' ambiguous sexual orientation came from Sam Simon, who proposed that Smithers should be gay, but little attention should be drawn to it.
In season 27, episode 17 "The Burns Cage" he came out as gay.
