No nudity. Very brief sexual innuendo. In one part one of the three amigos says that a plain is a boy plain, then they ask how he knows, then he says "didn't you see the little balls."
No gore. There's a lot of shooting, but none of the main characters "die." The shootings are on the same level of a Knotts Berry Farm show. (Shoot at some nameless bad-guy on a roof and he falls over, so you don't know if he's dead or just wounded).
There is a shit , a couple of hells, damns, a dick, and one god-damn. Mild language.
The first scene with the bandits shows them drinking tequila, running out of tequila and deciding to go rob the town of their tequila.No drugs, although the leader of the bad guys smokes a cigar briefly.
