I'm not a big fan of chain-letterish warnings like this, but it happened to my uncle and Snopes doesn't have an article verifying it yet. 

This one caught my elderly uncle by surprise. Over the last month he became a victim of a clever scam while out shopping. Simply going out to get building supplies has turned out to be quite traumatic. Don't be naive enough to think it couldn't happen to you or your friends.

Here's how the scam works: Two seriously good-looking 20-something year-old girls come over to your car as you are packing your shopping into the trunk. They both start wiping your windshield with a rag and Windex, all while wearing very suggestive clothing. It is impossible not to look. When you thank them and offer them a tip, they say "No" and instead ask you for a ride to McDonalds. You agree and they get in the backseat. On the way, they start undressing. Then one of them climbs over into the front seat and starts crawling all over you, while the other one steals your wallet.

Uncle Jack had his wallet stolen June 4th, 9th, 10th, twice on the 15th, 17th, 20th, 24th & 29th. Also July 1st , 4th, three times last Saturday and very likely again this upcoming weekend.  So spread the word and be careful! I am scared he will die of exhaustion before he learns not to trust strange young girls.

P.S. Wal-mart has wallets on sale $2.99 each...
