LOL Peter! Save the best for last....A friend set me up on a blind date once, the gentleman (LOOSE definition) had a baseball cap lined with tinfoil... so the aliens and the FBI couldn't read his brain-waves. They were also trying to sterilize him, so his shorts were lined with foil as well. I didn't stick around long enough for a look at THAT!!
All else fails, tell 'em you've got cramps....
