Posted by popular demand, here's a picture of my computer related injury:
The explanation:  I was sort of in a rush and I was taking my laptop out of the bag.  I guess I grabbed it by the side and gently let it slide out of my hand onto the table.  As it was sliding, its sharp corners sliced away a sliver of my left hand, leaving me bloodied and helpless.  After a night in the emergency room and the help of my wonderfully supportive wife Wendy, I was able to resume normal activity, including computer use. #technology
