* One of the many examples of his black humor is when he was hired by Disney Studios as a writer. Said job only lasted ''one day'' when Roy overheard Ellison pitching an animated film where several Disney characters invoked {{Rule34}}. Said movie wasn't a legitimate pitch, but it got him fired all the same.
* The fact that he trademarked his own name.
* There's a story about Ellison that Creator/StephenKing recounted in 1980's ''Danse Macabre'': in a plotting meeting for what became ''Film/StarTrekTheMotionPicture'', an executive repeatedly exhorted the writing staff to think bigger and bigger. Ellison thought for a few minutes, then suggested a plot where the ''Enterprise'' was sucked through a wormhole to the edge of all creation, where they found an enormous wall. Scotty figured out a way to breach the wall, at which point they are bathed in the luminous light of God Himself, peering back through the hole. When the executive claimed that this--''this''--wasn't big enough, Ellison flipped him the bird and walked out.
