The General (1926 film)/Funny

The Buster Keaton film

 * Johnnie Gray trying to fire, and later, avoid, the rail mortar.
 * There's also the time when Johnnie sees his girlfriend putting in a small piece of wood in the locomotive's furnace and he sarcastically presents an even small piece for her and looses his temper when she puts it in without recognizing the spirit of the gesture.
