A newly married couple are honeymooning in India. As they're walking through a bazaar they see a sign that reads: "Magic sandals. Guaranteed to improve your sex life."

The couple walk into the shop and are greeted by the shopkeeper. "These magic sandals," he tells the wife, "will increase your husband's sex drive and make him an accomplished lover." The wife tells the shopkeeper that her husband wears a size 10, and that he'd like to try them on.

So the husband sits down, puts on the sandals and gets a gleam in his eye that his wife has never seen before. The husband rips his pants off, bends the shopkeeper over the counter and goes to town.

Frantically the shopkeeper screams, "The sandals! You've got them on the wrong feet!"
