It's a Belgian, a Frenchman and an American who go to a hotel. Unfortunately, there is only one room with a double bed. They accept. Around midnight, there is the Frenchman who sneezes, but very very strong.
The other two moan and yell at him. About one o'clock, the American sneezes in his turn. After the two others get angry, the Belgian says:
- "Next time, we warn!"
Then, around two o'clock, the Belgian says:
- "Attention", the two others put under the cover, "I fart!"
