RAY: Here's the answer. My hint was, what was the kid wearing. Well, he was wearing a football uniform.
So when the question was 45 minus 8 and the kid answered 47, it was because if his team was on the opponent's 45 yard line, and lost 8 yards, they would be back at their own 47 yard line.
Similarly if they were on their 42 yard line and gained 15 yards, they wouldn't be in the 57 yard line, there is no 57. They'd be on the opponent's 43 yard line. Cute, eh?
TOM: Ohh that's good!
RAY: So who's our winner?
TOM: The winner this week is Robert Scott from Ypsilanti, Michigan, and for having his answer selected at random from among all the correct answers that we got, Robert's going to get a $26 gift certificate to the Shameless Commerce Division at cartalk.com, with which he can get a copy of our latest book called, Ask Click and Clack.
RAY: Congratulations, Robert!
