I once helped 4 other guys pick up a Honda Civic as a prank (we put it sideways in front of someone's garage). I was the last to let go and I swear I pulled every muscle in my upper body. Lesson learned... from now on, when I come up with pranks, my minions will do all the heavy lifting.

All that aside, I used to work in appliance delivery. We wouldn't move anything toher than the haul-away appliance out, the new appliance in, and connect water lines. We weren't responsible for moving anything in the way. we didn't want to be responsible for anything we shouldn't have been doing.
