was a character on Sesame Street who was dubbed "America's Favorite Game Show Host." This nattily attired character is easily excitable and is perpetually shouting, and resembles Canadian/U.S. quizmaster Jim Perry (of Card Sharks fame).
Apparently Guy Smiley is not his real name - in one Sesame Street skit, he stated: "Well, my name's Guy Smiley, and they call me that because I changed it from Bernie Liederkrantz!"
