A Conversation between Buddies

I overheard the following conversation yesterday, while Jack was trying to show Caleb how to hit a golf ball off a tee:

Jack: Caleb, stand back, so you don't get whacked in the head with the club.

Caleb: It's okay, Jack, I have a really tough head.

Jack: Yeah, but this would really put a crack in it.

After taking to a moment to ponder his good buddy's wise words and probably weighing the pros and cons of actually being whacked in the head with an iron club, Caleb stepped back and said: Okay, buddy, I better move out of the way.

Thank goodness, good sense prevailed!
