Cotton the fabric of our lives

Last April fools I decided to actually pull a prank off, since nobody at my job ever tries to. I was reading Catch 22 at the time and there is a scene were Milo can't sell his cotton, so he tries to cover it in chocolate and sell it to the soldiers. I thought this was pretty funny, so I bought some cotton balls and melted a pan full of chocolate and made a plate of chocolate coated cotton confections for my coworkers. I did a good job making them, and they looked delicious! It went over pretty well at first, people would bite into one and laugh as they pulled bits of cotton from their mouths. Then Gus came along and swallowed an entire cotton ball. He apparently said "the chocolate was good, but the filling was a bit odd". When someone told him it was a prank and that he had just eaten cotton, he sorta flipped out. He threw my plate against the wall and said he was going to "kick my bum". I apologized, but he doesn't strike me as the forgiving type. Turns out his name wasn't even Gus. He had double bypass surgery two weeks later.
