Considering the fact that visitors to my shanty town sleep in sleeping bags, I'd probably roll them up, tie the bag shut tightly, then beat the shit out of it with a crowbar.
I would stop every now and then for a glass of shine, perhaps a cigar, then continue with the fun until the bag didn't move as much.
Then I'd fasten some rocks onto it and dump it in the lake.
Shit, I might even do that if they aren't fucking each other just so I have a spare bag to stomp on.
