Did something close to it Seamus.
I used to cover Canada as part of my sales territory and it involved a lot of one night trips to Toronto and Montreal. A Customs Agent at the airport was suspicious about my frequent short trips and went through everything in my purse and overnight bag. I had stated on the Customs Form that I hadn't purchased anything in Canada to take back into the US.
So he rummages through my things and finds a small bag - I had bought a birthday card and mailed it from Canada. In the bag were my dirty undies. "AHHA!" he shouts. "I thought you said you didn't buy anything? What's in this bag?" "My soiled undies" I replied and he quickly put it all back in and sent me through.
Bet he washed his hands afterwards.
