The thing is, graycardinal appears to be saying that I have to give him apples if I guess correctly - preferably in the form of a pie with added ice cream.

That at first seems rather unfair. However, the 'apples' in the phrase 'How do you like them apples?' are in fact projectiles thrown at an enemy, which I'm more than willing to do. I believe you both live in the same city - if I do guess correctly could I nominate you as my proxy to go and chuck a Red Delicious or two at graycardinal? I'd be most grateful.
