Are you crazy??

This happened when I was in high school - 15 years ago. In high school I lived in a small dormitory. There lived about 70 people. Everyone knew each other very well. Mario Paul and Peter lived in room 28. Paul used to go to sleep earlier and get up earlier than the rest of the residents. He was always the first at breakfast. He used to set up the alarm clock at 6:00 a.m. Wake-up call for the whole dormitory was set at 6:30. One day, Mario and Peter decided to make a joke Paul. It was winter time, When Paul went to sleep, they switch over his watch about four hours ahead. So when the alarm clock rang was actually 2 a.m. in the middle of the night. 

Paul thought is 6 a.m., so he got up, got dressed and went down to breakfast. The canteen was closed, so Paul went to the maintainer performing night duty for the key to the canteen. Sleepy and upset maintainer said:

“Are you crazy? For what purpose do you need this key now?! Go to sleep is 2 a.m.”
