Going for a Swim

A golfer is playing a round of golf with his buddies. On the sixth hole, he proceeds to splash five balls in a row into the water.

Frustrated over his poor golfing ability, and about ready to hit somebody, he heaves his golf clubs into the water, and begins to walk off the course.

Then all of a sudden, he turns around and jumps back in the lake, his buddies apparently thinking he is going to retrieve his clubs.

When he comes out of the water, he doesn't have his clubs and begins to walk off the course.

One of his buddies asks, "Why did you jump into the lake?"

He responds, "I left my car keys in the bag."
