Whos driving

This is a classic pun. The setup makes you expect an answer related to one of the two Mexicans, but the punchline takes it in a different direction by using the homophone "whose" for "who's".

• Cop
• Mexican
• Car
• Police
• Driver
• Vehicle

• What do you call a Mexican who lost his car? - Carlos.
• There's a Mexican, Brazilian, and Cuban in a S60. Who's driving?
• A Mexican is drunk and he has a passenger in the car, and the passenger asked, "Where are we going?" The Mexican says, "I'm not driving, the drunk guy is."
• If there are 4 Mexicans in a van, which of them is driving? None of them. Immigration service is.
