Three-In-A-Row Smith

Three-In-A-Row Smith is the world's greatest tic-tac-toe player who appears in Episode 2327 of Sesame Street.

He visits Sesame Street and challenges various residents to several dozen rounds of tic-tac-toe. He hangs up all his victories on the walls of Hooper's Store, having not lost a single round yet. He becomes disappointed, as none of the games on Sesame Street have made a lasting impression on him. That is, until Snuffy challenges him to a match using his giant tic-tac-toe board.
