Dangerous Dan McFoo is a 1939 Warner Bros. Merrie Melodies cartoon directed by Tex Avery.
[3] The title is based on a 1907 poem by Robert W. Service entitled "The Shooting of Dan McGrew".
Dan, an anthropomorphic puppy, is in the rear of the arctic "Malibu Saloon" playing pinball.
A boxing match ensues, and a streetcar plunges into the saloon through the swinging doors, the conductor ringing its bell at the start of each round.
In round 2, after getting a shave and a haircut, the villain gains the upper hand, knocking Dan unconscious.
