RAY: A listener sent in a few basic facts for a puzzler.

TOM: And let me guess. You've embellished and obfuscated?

RAY: Of course. He said, "Some years ago, I was in the service stationed overseas. While I was there, I decided it would be fun to buy a motorcycle, the intention being that I would drive it while I was stationed in Europe. When my tour of duty was over, I would ship the bike back to the United States.

"While I'm at the motorcycle shop, the owner, recognizing that I'm a serviceman, says, 'You're going to ship this back to the States when your tour is over?'

"And I say, 'Yeah, as a matter of fact, I am.'

"He says, 'There's something you'll have to change before you can drive this thing in America.'

"I ask him, 'Can I buy this thing from you?'

"He says, 'No, I don't have one -- but you'll certainly have no trouble getting one when you get home.'

"The question is, what did I have to change on this bike before it would be legal to drive in America?"
