First, cover a friend in meat!
Next, tie them with kite string!
Leave them in the sun for three days!
When they're done, beat the pigeons away and play!
It's best to play meat doll when you're little. If you do it when you've grown up, your friends will be bigger too, and you'll need lots of kite string and raw meat. And if the neighbors see you, the effect will likely be lost.
