From Modern Drunkard Magazine (I kid you not):
"Jackie Gleason didn’t always fall short of his boasts. He and fellow heavyweight drunkard Orson Welles were drinking up a storm at the Stork Club when Orson Welles broached the subject of Shakespeare. Jackie claimed to know much of the Bard’s work by heart, and Welles, doubting his Brooklyn grade-school dropout’s boast, intentionally misquoted an obscure line from Aeschylus. Jackie Gleason immediately corrected him, prompting Welles to declare, “You’re the Great One!” The name stuck."
