If I ate three solid meals of nothing but Cocoa Puffs everyday, would it still be called three "square meals?" Because, honestly, there's nothing square about a meal made of Cocoa Puffs. The yuumy, chocolately puffs themselves are little round balls. The bowl from which I eat them is also round, as is the spoon - no squared off edges. The jug of milk, while not perfectly round, is certainly not sqaure. I'm not much of a toast eater, so we can count that out. The only thing that hints of square-ness at this meal is the box of Cocoa Puffs itself, but I'm not eating the box, so it doesn't count.
I think this is a great example of how one could go about daily life, surviving on nothing but three hearty "round" meals a day. Cocoa Puffs. The breakfast of champions.
I actually had Reese's Puffs for breakfast, but the same concept still applies, wanker. Back off.
