Once a village bum went on an airplane for the first time. After some turbulence, the village bum asked the man sitting next to him to open the window so he can throw up.
The man told him the window cannot be opened so the village bum started beating up the man.
Soon a flight attendant came and asked him the reason for his behavior. After listening to his complaint the flight attendant told him about the barf bag. After a while, the flight attendant came and saw all the passengers barfing. Since the village bum was the only one not throwing up the flight attendant asked him what had happened.
To this, the village bum replied that as he was throwing up everyone stared at him so being embarrassed he drank it back.
