Cereal. I'd just keep pouring more cereal in so they can't ever execute me, but if they do interrupt my last meal, I'd then be off to take a massive dump which will take a long time and give me enough time for a very poorly thought out escape plan.
Lol, stop all of this escape stuff. If you escaped it wouldn't be your last meal, would it?
