Nasty Golf Shot

John's not a great golfer - in fact, he stinks. But he's always working on his game, trying to improve. One afternoon, after a typically crappy round of golf, John is interrupted by a police officer as he's throwing his clubs in the car. "Did you tee off on the 17th hole about 20 minutes ago?"

"Why, yes I did officer." John replied.

"Did you by any chance hook your ball over the trees to the left, out of bounds?" asked the officer.

"Yep, I believe I did." John answered. "How'd you know?"

"Well," said the officer in a very serious tone, "Your golf ball flew out onto the highway and crashed through a car's windshield. The driver lost control, causing a 5 car pile-up and a small explosion. Three people went to the hospital with injuries. I'd like to know what you're going to do about it?"

John sat there, seemingly saddened by the devastation caused by his errant tee shot. After much though, the he responded...

"I think I'll aim more to the right, close up my stance, tighten my grip and roll my right thumb over a bit."
