I did that recently with one of those big boxes of goldfish crackers. I downed it in two sittings over two days. Which is a total of 4,000 calories of cheesy crackers (on top of my normal helathy food). Yeah, I regretted it, I only did it because I havent eaten like a retard in like a decade, and thought it would be fun. I guess it sort of was... or as fun as feeling like crap can get I guess.
