Burn him alive.
Ah yes, the old tried and true way. Me, I’m into tossing this kind off bridges. You know bridges on the order of The Golden Gate and The George Washington( I live in NJ, used to commute over the GW.)
The Golden Gate is 220 feet off the water in about five seconds you’d hit the water at 5 mph. You’d hit the water like you were hitting a brick wall.
The GW is 212 feet off the water. You’d hit the water at about the same speed.
