The Gallopin' Gaucho - Mickey Mouse cartoon

The Gallopin' Gaucho (1928) starring Mickey Mouse, Minnie, Black Pete

"The Gallopin' Gaucho" is a parody of Douglas Fairbanks' "The Gaucho" - which probably explains why Mickey's smoking a cigarette, drinking beer, etc.

He rides into the "Cantino Argentino", romances barmaid Minnie, who's kidnapped by Black Pete! So Mickey rides to the rescue on his (drunken) steed, and duels Pete with swords!
