Do you want to hear a riddle I made up?

There are always people with a strong feeling that they are very humoristic. Feeling that they have the best joke or riddle on the room. People with a self-confidence with the size of the universe. Whenever I need to be on the same room as these kind of people it is always a challenge to keep inside the room. They try to manage the room discussion. Fortunately this is not a daily challenge but sometimes happen. What to do when it happens? 2 options: if does not impact you or your work just smile and shake your head up and down. If it impacts go to fight since the first second!!!!
