By counting dead babies.
It's a variation on counting sheep. You just imagine all the
children who have been gunned down in this country over the past few
years. That's hundreds & thousands of America's
children––children of all ages, all races, all
temperaments; good children & bad children; loud children &
quiet children; thousands & thousands of beautiful, dead children.
Then you imagine the kids getting up & jumping one by one over a
fence. This puts you to sleep, you see.
Except that they can't jump over the fence because they're dead.
Those bad kids! Maybe the gun guys had better stick to sheep.
Sweet
dreams, gun guys!
