In the original theatrical release, instead of the usual roaring lion in MGM's studio logo, the lion is drunk and belches. Then the camera pans to the side to reveal that the McKenzie Brothers (the main characters in this movie) are playing with the lion's tail. When the lion gets angry, they leave to another room to introduce the movie.
As the end credits roll, we see Bob and Doug drive away with a beer truck. After a few seconds, the film cuts to The Great White North set and Bob and Doug give their explanations for the various film credits.
