Two drivers driving along a road looking for a place to stop and have a picnic.
The first driver says, "Let's stop here, and have our picnic under that tree."
The other one says, "No! Let's have it right here in the middle of the road."
They fought for a bit, but finally agreed to have it in the middle of the road.
All of a sudden, a car comes speeding towards them and has to swerve into the tree to keep from hitting them.
The second driver says, "See? If we were under that tree, we'd be dead by now!"
