What Kind of Maniac Would Slice a Rectangle Cake Diagonally?

We were having a little going away party for a co-worker when he started slicing the cake in a way that would make most OCD go insane.

Seriously, who does this?

Then again, now that I think of this, maybe it's not such a bad idea. You'd probably get more cake per area and, depending on how you slice it, you're not stuck with a corner piece that has too much frosting.

Either way, this is the type of thing you watch out for when seeing if someone isn't quite right in the head.
