We still have a set in the family. If I didn't, I'd buy them from you. Instead, I'm going to urge you not to sell them unless you're in dire straits.

My brother and I trade them off every few years. He had them for most of his college experience and invented some sort of drinking game to go with it. Last time they were in my possession, I accidentally spiked a friend in the foot when neither of us were paying attention at the worst possible moment.
