Dumb and Dumber is a 1994 American comedy film starring Jim Carrey as Lloyd Christmas and Jeff Daniels as Harry Dunne, and its trailers have long been reused online as sources for short reaction clips. This alarm snippet circulated mainly as a phone ringtone, credited to Ringtone Maker in its file metadata, before being uploaded to soundboards as a quick meme effect. Its lasting appeal is simple timing: a familiar movie name attached to an instantly recognisable alert tone that creators can drop into almost any funny emergency scene.
