There is indeed an 'Are you a Turtle?' card in the Smithsonian (or was, last time I was there). Legend has it that one of the astronauts flashed it to a member of the ground crew during a live TV broadcast, which would have meant that the crew member either had to say 'You bet your sweet ass I am' on TV, or stand all of the thousands of people watching the telecast a drink.

IIRC, the legend says that the crew member he switched his microphone off before answering.

Has anyone tried one of these?

Anyone else think this looks like the Batmobile? (particularly the animated TV series version)
