Back in the 19th Century, a bank in the Oklahoma Territory was robbed by a Mexican bandit. The Mexican promptly hightailed it for the Rio Grande. A US Marshal went after him, determined to bring the money back. The first town he came to in Mexico, he picked up a local who had a reputation as a great tracker.
The two of them continued on the trail of the bank robber and cornered and captured him in a small Mexican village. The marshal searched the bank robber's room and his saddlebags, but he didn't find the money. He went down into the main room of the cantina where his Mexican tracker was holding the crook.
"What did you do with the money?" he asked.
"No habla Inglese, senor." The marshal turned to his Mexican tracker.
"What'd he say?"
"He said, 'I don't speak English,' " said the tracker.
The marshal said, "Translate for me, please. Ask him what he did with the money he stole."
The tracker did. The bandit replied. The tracker said, "He says, 'Go to hell," senor."
The marshal slapped the bank robber across the face three or four times. "Ask him again. What did he do with the money?"
The tracker did. The Mexican spat at the marshal and said something. "He says, 'Go have sex with a donkey and then watch the donkey screw your mother,' senor."
The marshal took out his pistol, cocked it and stuck it under the bank robber's chin. "Tell him that if he doesn't tell me where the money is, I'm going to blow his head off."
The Mexican tracker told the criminal, "The marshal says that if you don't tell him where you hid the money, he's going to blow your head off, compadre."
The Mexican bandit blurted, "Tell him it's in the well in the back of the cantina, tied to a fishing line secured to the well cover!"
The tracker said, "He says, 'You haven't got the cojones to blow my head off! Go ahead and shoot me! I dare you!' "
