Obviously, most Three Stooges shorts feature characters named Moe, Larry & Curly/Shemp/Joe. But not all of them.
In WOMAN HATERS, the characters are Tom, Jim & Jack.
In GOOFS AND SADDLES, the characters are Will Bill Hiccup, Just Plain Bill & Buffalo Billius.
In SWEET AND HOT, they're Dr. Hugo Gansamacher, Larry & Joe.
Are there any others?
(I'm disregarding feature films because they're another matter altogether, especially where the Stooges have brief cameos as unnamed characters. ROCKIN' IN THE ROCKIES may be worth a mention, though, with Moe being called Shorty Williams.)
