A logger is driving down the highway and sees two botanists trying to measure the height of a small pine tree.
Their tape measure is not long enough so one botanist stands on the shoulders of the other and attempts to extend the tape to the tree top but it is not long enough.
While trying, he falls to the ground.
They attempt this about five times and each time the top botanist falls.
The logger is laughing but feels sorry for the pair, gets out of his truck, takes out an electric saw and cuts down the tree.
The botanists are looking at him like he is crazy.
He then takes a tape measure and measures the tree.
"OK guys, the tree is 14' 6." He then gets in his truck and drives away.
The two botanists are stunned and speechless.
Finally one says to the other ,"How do you like that, we are trying to measure the height of the tree and that stupid jerk measures the width."
