An American tourist in Mexico saw a donkey rental place and decided to try it. "I want to rent a donkey," he said.
The proprietor replied, "We don't call them donkeys here--they're asses. And the only ass I have left is a little weird. You have to scratch him to make him stop."
"No big deal," thinks the American and takes his new ass for a spin. Seeing a hotdog stand, he stopped and ordered a hotdog. The proprietor replied, "We don't call them hotdogs here--they're wieners." Meanwhile, his donkey started to wander off.
He turned to another tourist and asked, "Would you mind holding my wiener while I scratch my ass?
