Thinkpad nick
I took my Thinkpad T60 to the airport, took it out of its protective case and put it in one of those trays at the security line. I needed a few trays for other stuff, so things got a bit cramped, trays were moshing with other trays as they were pushed forward towards the x-ray machine. The tray with the T60 fell off the table and the laptop crashed upside down on the tile floor, three feet below.
It survived with only a small nick on an outside corner of the LCD bezel.
The laptop was in standby at the time. The person behind me thought my laptop was toast, but I showed her the lit moon and we both knew my T60 was going to be alright.
