I would never in a million billion years spend $100 on a bottle of wine. That's about a liter. I can buy a 2-liter bottle of Sam's version of Sierra Mist for 64 cents. That's 32 cents a liter, 300 times cheaper and a helluva lot better tasting!
I vaguely remember the $100 bet, but I knew I would never need to pay it off and figured you'd forget. You are a good man. My suggestion would be to give the $100 to some local agency that helps the poor.
