Among the funny prank videos on the YouTube website is this hidden gem. This is another of those funny prank videos that deals with the embarrassing but hilarious subject of farting. In this clip, a young man is taking his driving test. Somebody has placed a hidden camera and a remote controlled fart machine in the back of the car. As the examiner is instructing the young man, a series of wet fart noises occur. What makes this clip more hilarious than many of the other funny prank videos on YouTube is the examiner's reaction. Every time a fart noise occurs, his head snaps round and he gives the young man a dirty look. The young man who is driving begins to laugh uncontrollably. At the end, he asks the examiner if he would like him to open the window. In a voice that clearly shows his irritation the examiner replies "Yes, I'd appreciate that." Amusingly, the young man in question fails his test. This is a treasure among funny prank videos because the examiner, utterly appalled at the blatant rudeness, is obviously struggling not to reprimand the young man driving the car. If I were the examiner, I would probably have told the young man to stop the car and left.
