Apple Corer?

I once sold what I thought was an apple corer to a guy. He thought it was an apple corer too, since that is what the sign said. I later found out that it was really a cake server and someone (yes, it was me) had left the wrong sign on them. Just for your information, a cake server looks nothing at all like an apple corer. I hope he figured it out. Guy, if you are reading this, sorry.
