This is one of those stories that loses something in hearing it second hand. You just had to be there to appreciate how perversely funny this particular Mike trick really was. However, in the interest of preserving a bit of history, I will attempt to record the event as follows:

It was a lazy afternoon at our house on 806 Dupont street. I was employing my usual tactic on days like this: Lay on Mike's bed and talk to him until he stopped studying and started doing something more interesting, or until I fell asleep, whichever came first. All to often the latter was the case, but on this particular day I was in luck.

It wasn't long before Mike had stopped studying and started looking around for something to do. About this time Chris came over from his room across the hallway and joined the conversation. I am not sure what we were talking about, but it is a certainty that it was A) pointless, and B) related to engineering, cars, or computers. We had a lot of discussions like that.

Eventually the focus of the discussion turned to a small computer fan that was sitting on Mike's dresser. About one inch square, this little fan was the subject of sales negotiations between Mike, who wanted to sell it, and Chris, who wanted it for his video card but was too cheap to pay $5 for it.

It wasn't long before Mike made the discovery that he could make the fan turn by blowing into the blades. In fact if he blew really hard he could make it turn really fast. And if he blew really, really hard it would go faster still. And if he blew really, really, REALLY hard? Well, Mike never found how fast it could go because he got those fan blades just a little too close to his lower lip. His new discovery was that those little fan blades are very sharp, and if you stick your lip in them while they are spinning at 6000 RPM it is going to hurt.

He ended up having to pry the fan from his lower lip, and spent the next 5 minutes sticking tissues in his mouth in an attempt to stop the bleeding. To add insult to his injury, Chris and I were rolling on the ground laughing and giving him no sympathy at all. Just then Keith came in the room to see what was so funny.

"Damn, Mike, you broke it!"
"No way, let me see."
Sure enough, he not only got the fan stuck on his lip, but managed to jam it on there so far that the miniature bearing gave out and the fan blade broke away from the body. Mike eventually recovered fully from his injury, but his hopes of extracting $5 from Chris were dashed by this unfortunate accident.
