Cake with no knife? Are they insane?

So I'm sitting here at work and realizing I'm hungry. I go to the snack room since there is always food in there. Not to my surprise, there is a cake sitting on the counter. This seems exciting, but there are no knives or plates to be found. Now, I could eat cake without a plate and just use a napkin. No big deal. But eat cake without a knife? How can one do that? I'm going to have to leave a note on the office bulletin board (if we had one).
