He felt ___________________________________. [originaltext] Two businessmen we

Two businessmen were invited to dinner at the home of a college professor. One of the men did not have much education and was worried that he might make, a fool of himself, but his friend said, "Don’t worry. Just do what I do, and don’t talk about anything that you don’t really understand.
   The first man managed to get through the dinner successfully, but by the end of the evening he had had a lot to drink, and began to get careless.
   A guest asked him whether he liked Shakespeare, and he answered confidently, "It’s very pleasant, but I prefer Caco Cola." There was an uncomfortable silence in the room, and soon people began to leave.
   When the two friends were out of the house, the second man said to his friend, "You certainly made a fool of yourself making that silly remark about Caeo Cola."
   "What do you mean?" asked the other man. "What was wrong with it?"
   "Everybody knows that Shakespeare isn’t a drink," his friend replied, "It’s a kind of cheese."
How did the first man feel when he was invited to the party?
