Richard and the Bikini-clad Sisters
RAY: He saw something on one of them, he didn't see it on the other, and he knew something that the average citizen probably doesn't know: After 1972 doctors stopped giving people smallpox vaccines.
So, one sister was born before 1972 and had a smallpox vaccination.
Usually they're done on your shoulder, but in some cases for women they actually put them on their hips. That's why they had to be wearing bikinis for the scar to be seen.
Of course, the sister born after 1972 had no such scar.
Do we have a winner?
TOM: We certainly do. The winner this week is Melanie McClosky from Hood River, Oregon. And for having her answer selected at random from among all the correct answers that we got, Melanie gets a 26-dollar gift certificate to the Shameless Commerce Division at cartalk.com, with which she can pick up the brand-new Car Talk football jersey.
RAY: Oh yeah, we had our name stitched under the back of our jerseys, but I guess there was a little confusion at the factory or something, I don't know what happened. Because the back of my brother's shirt says, "Knucklehead."
