Story from my local B&M. A kid (college student about 18/19) went into the shop one day and picked out a Camacho Triple Maduro. He was warned that this was only for experienced smokers but he said he could handle it. I believe he was trying to be macho with a group of friends.
Now I wasn't there at the time but from what I have been told, he smoked the 6x60 cigar about 1/2 way down in about 45 minutes. He stood up and ran towards the door. He did not make it. Needless to say, he was cleaning his puke off the shop floor and windows.
