Main characters of two comedy movies, Bill and Ted's Excellent Adventure (1989) and Bill and Ted's Bogus Journey (1991), played by Keanu Reeves and Alex Winter. The movies, on which a television series was based, tell the story of two seemingly dumb teenagers who travel through time. Main joke of the movies SEEMS TO BE the way Bill and Ted speak, using the words 'excellent' and 'dude' about every alternate sentence.
