Hook him to a generator and tap him into the house power so your energy bill will go down.
Duct tape his head to the wall...making a banishment sigil with the duct tape.
...there's nothing you can't fix with duct tape.
pour holy water on him, smack him with a cross, bash him with a chalice and get a christian kung-fu priest to kick his ghostly ***
Shut his head in a door.
Quick! Hold his head still and see if his body spins.
Try a kick to the bollocks.
try a c-collar to help keep it in neutral in-line position and have a coupla burly paramedics hold it there.
The head will eventually come to a stop - if he starts heaving up green stuff,get out of there fast!
Lol .. Clamp it :-)
