A man was watching from the sidewalk and couldn't believe how hard these men were working, but couldn't understand what they were doing. Finally he had to ask them.
He said to the hole digger "I appreciate how hard you work, but what are you doing, you dig a hole, and your partner comes behind you and fills it up again."
The hole digger replied "Oh yeah, must look funny, but the guy who plants the trees is sick today."
