7D with 17-40L: I bought a Lowepro slingshot bag and for whatever reason didn't zip up the main compartment
flap, nor did I notice it was undone when I picked the bag up out of the car. Swung it onto my back and thud- camera falls about a metre and a half onto a ballast drive. A metre further back and it would have landed on grass. No real damage, a few small paint marks, small mark on the lens filter and a mark on the lens hood mount, and some marks on the CF card door. Could have been worse, but I was pissed off because the camera was pristine until that, and not very old

Also, some years ago when I was still a youngster I had an old Pentax MX film camera my Dad let me use..... One frosty night in a disused railway station whilst trying some bulb shots I slid on the frosty rail whilst crossing the track and the tripod and camera went over, whacking the front of the lens barrel on the rail and making a nice dent. I had to replace the lens and hope my dad didn't notice the different serial number, which was very prominent on the Pentax M series lenses!
