Cheese Plugs

Today, a friend of mine was explaining to me and my co-worker that the restrooms are not clean at his place of employment.  He could not think of sitting on the toilet, so he said he went to the cafeteria and purchased 2 cubes of cheese to clog him up.  I haven't ever heard about using cheese plugs, but I am listening.........  About now I had to ask if he was eating the cheese or using it as a butt plug.  Of course, he was eating it, but that is not how it came out, or I mean how his words came out.  We are still laughing at this one.
