I have a bit of a funny story about can crushers, (densifiers). A local brewer (Molsons) used to have this old hydraulically activated can densifier under the can line at the plant. As one of the local hydraulic houses we used to get sent this thing every few years to rebuild and reseal it. It had a large hopper that recieved rejected can from the can line. They would fall down the chute into the hopper. When the level of cans reached a photo eye, the system would cycle, about 4 or 5 cycles and the unit would spit out a square block of crushed cans about 2 foot square. People here probably have seen these types of densifiers.
Anyways, one christmas we were sent this thing, I was tasked with cleaning it before we pulled the cylinders and valve manifolds. I pulled out over 48 full and partially full cans that had been lodged in various parts of the machine. Who knows how long these beer had been stuck here, covered in dried stale beer that sprays from the machine during the cycle. As well, I found a few roaches that had been attracted to the beer runnoff.
Along comes the company drunk, "hey free beer" and he proceeds to wash them all off and starts getting stinking drunk on stale and skunky beer.
Just goes to show truth in the statement " I have never met a beer that I didn't like"
