Hi-Ho Silver comes from the Lone Ranger, where the masked hero used it to urge his horse Silver onward, and Ace Ventura borrows the line for comic effect in the 1994 film Ace Ventura: Pet Detective. Jim Carrey plays the eccentric pet detective whose overacting turns a familiar western catchphrase into a joke about misplaced heroism. The clip spread through soundboards and meme edits because the shout is instantly recognisable even without the film context, and creators still use it to mock-celebrate entrances, wins and ridiculous rescues.
