Years ago I saw a western comedy movie in which, in an early scene, a group of train robbers stole a safe from a train. They were unable to blow it open, so they dragged it up a tall mountain and threw it down the mountain, hoping that it would break open on the rocks. Instead, it rolled into a lake and they had some trouble finding it. This movie was pretty funny, but I can't remember the name of it. Can you help?
Thanks.
