It was about 1976, some friends of mine had one of those 3-4 ft bongs with a giant bowl. Two of the people worked for me at the time, and they decided they were going to pull one over on me after we'd just spent the afternoon drinking all kinds of different booze. Well, they loaded up the bong, overloaded should I say, I took the whole bowl, inhaled, and then puked back into the bong!!!! You see, they were giggling because they gave me a monster bowl and wanted to laugh at my reaction when it blew the top of my head off. Well we all know he who laughs last laughs best!!!!
