How did he break his collarbone?

I heard a similar story about a clogged up can of Aqua-net. Wife sprays the can into the toilet to unclog it and then it sticks open so she holds the can in there until it is exhausted. Hubby takes the mandatory smoke break while unloading himself and blows himself right off the can.
Or the guy that is working on a highly pitched roof so he ties himself off to the truck bumper that on the backside...which is then used for the lunch run.. and pulls the guy up and over and off the roof!
Or the drunk guy sleeping naked in his sleeping car and his buddies fold up his cot and strap it up, trapping his bare *** against the window as the train comes into a station....
