Even if the story is true... It takes 3 failures of both gun safety and intelligence to get there:
1. Manage to be stupid enough to not only keep your shotgun loaded, but with a round chambered.
2. Manage not to have a safety on.
3. Ask someone barely big enough to carry the item to you.
Ok, maybe you do keep your gun loaded, I personally wouldn't unless I was in a 'warzone' or had immediate cause to have a loaded gun handy. Heck with things like clips of ammo and speed loaders the need to keep a weapon loaded is very very low. Even classic break-open (ie breech loading) shotguns aren't usually kept loaded as it takes only a second or two to slap in a cartridge and be ready to fire.
However if you fail all three steps then you have truly proved yourself an idiot and certainly should never have owned a firearm.
