I know a grumpy old man who was once at a party (a New Years celebration if my memory serves me). This guy was in a dimly lit room with the party going on around him and picked up off of a coffee table what he thought to be a doughnut, taking a bite. At this point his horrified wife grabbed his arm saying, "Joe, you just took a bite out of the cheese ball!" Joe was too embarrased to put the bitten cheese ball back on the tray so he continued to eat the entire thing, grimacing the whole time. I don't think I would have been able to eat the whole thing without vomiting.
