A newbie steps up to the first tee and opens up a new sleeve of ProV1's. Hits the first ball into the water and takes out a new ball. Hits that one into the water. Takes out the 3rd Pro V1 and hits it into the woods. Goes back to the bag for a new sleeve. His buddy says "Hey, why don't you just use an old ball"? He says, "I don't have any".
