Ha! I think this is a great idea!
I could easily go 'lee or 'ler, but I don't know how long I could hold out. On the one hand, I'm very stubborn, but on the other I'm also very ticklish. I would be extremely disappointed in myself if I cracked too easily.
I also love the idea of the slow build-up. The uncertainty. The anticipation. The fear. It would really get the ol' heart a pumpin'.
