Is it too late to get in? Even if it is I say five and then two or three bites into sixth, I think you're underestimating how heavy that McDonald's grease is going to sit in a stomach that hasn't had solids in a while. Or maybe you're overestimating, you haven't estimated anything in this thread, but I know that whatever personal estimation you've made is wrong. Of course it all depends on the time frame you're putting this into. If you put all night into it you could definitely eat them all, but if it's a roughly 45 minute sitting I think my guess will stand.
