Think I'll get a pair of those thongs for next trade show. That way when people aren't sure if they remember talking to me I can say. "I was the guy wearing the tool thong". That should do the trick.
Maybe you could try the same trick for getting wax out of your carpet... place a few paper towels over the affected area and hit it with your iron. Melts the wax, and gets absorbed into the paper towel?
