There were two guys working for the

city. One would dig a hole — he would dig, dig, dig.
The other
would come behind him and fill the hole — fill, fill, fill.
These two
men worked furiously; one digging a hole, the other filling
it up
again.
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.”
