This is [supposedly] a true story, it happened in a small town of the
province of Quebec,  Canada, in October 1996. They showed the video
surveillance tape on the news,  and even the anchorman was laughing through
it.
 
A robber came into a convenience store wearing a ski mask and a gun wanting
to empty the cash register. He took the clerk to the backstore and locked
her up in the fridge. Unfortunately, when he came back to the front of the
store, a customer had come in. So he took *off* the ski mask and the gloves,
and 
pretended to be filling in for the clerk. The customer wanted a lottery
ticket, so he tried to help her out, by pressing a whole bunch of buttons on
the machine (thus leaving fingerprints everywhere), but the machine was not
cooperating.  
 
Meanwhile, another customer walks in. Finally, he tells the first customer
(after about 5 minutes of close-up shots from the camera) that the machine
is  not working and that he won't be able to help her. The robber *makes the
sale* to the second customer and he leaves as well.  
 
The robber then puts back on his gloves to take the money (after touching
just  about everything in sight *without* gloves), and hides his face with
the palm of his hands as he is leaving. This scene lasted well over 10
minutes, during which, you see and hear the robber as well as in a movie.
The day after 
excerpts of the tape were aired, the phones at the police station were
ringing  off the hook. Apparently, even though no reward had been offered,
people thought he was too stupid to deserve anything else! 
 
He had to turn himself in  that same day.
