Someone brought in a bunch of cheesecake on Friday, and I didn't want to each a bunch of cheesecake and Stacy didn't want to eat a bunch of cheesecake . . . so Stacy gave me twenty dollars to hold, and if she ate any cheesecake, then I wouldn't return it, and I gave her twenty dollars and the deal was the same, but then we thought we'd better involve an unbiased third party . . . so we gave the money to Liz to hold in escrow, and it worked like a charm-- neither of us caved-- and it appears to be a brilliant strategy for eating healthy . . . unless, of course, you do break down and eat a slice of cheesecake, because then you're not going to pay twenty dollars for one slice, so to cut your losses you'll probably go berserk and eat five slices of cheesecake so that they only cost you four dollars per slice.
