Letting someone hit a golf ball of a tee placed in your mouth as you lie on the ground is the golf equivalent of the trust fall. It's big enough of a deal to let a sober, skilled golfer do it. The amount of trust increases with the decrease in skill, as well the increase in the amount of liquor consumed and/or the age of the person swinging the club.
Needless to say, this dad has -- had? -- a lot of trust in his little boy to let become a human tee for him. It didn't go well.
The little boy -- thankfully swinging plastic clubs -- delivers a chunk swing, right into his dad's head.
