Marx Brothers: Go West (1940)

All 3 bros are going "west" but all are sort on money. They go there to dig gold that is "laying all over the streets". Right at the station they pull a gig with money that makes you rolling laughing.
Oe they get to the wets they manadge to get a deed to a useless land that turns out nto so useless. 50.000 dollars for it from the railroad company. but they also manadge to loose it. the railroad company man arrives and tries to buy it but they bargain well pretending to be a fake oil company.
They have trouble gettign the moeny for the deed however as the local bandits simply steal the deed. This whole scene is filled with songs and music induedos. So small scene screaches a lot though the 20 minute period. They breake in at night to steal the deed but are discovered by ladies (for hire). The ladies decide to "keep" them in while bandit comes but end up having good fun. the bandit get there in time, but they destroy the safe and stela the deed. The lover that seems to be a stand in for zeppo in MGM movies saves them and they go riding singing "riding in the raid, we dont know where, but horses know so we dont care". whoever came up with those lyrics should shoot himself now. They get to indian camp and make toruble there talking to the chief. Groucho tries to run his regular routine of trying to sell some pearls and the indian replies "no like. me want cadillac sedan".
The conpany then steals a train with crooks inside it to get to New York, beats crooks up, improvise fuel and runs the train down into a building and still gets to new York. Good guys win again, and this time, big money.

Even with all the singing scenes its a great movie, go see it.
