You can play as a literal cigarette butt in GTA — here's how.

In the Game Boy Color version of the original GTA, entering 'SUMNER' as a name unlocks 16 secret playable characters, including one called 'Dog End' — British slang for a cigarette butt. His face, like all the secret characters, is actually a photo of one of the real developers at Tarantula Studios who made the port.
