On a narrow mountain’s road a man saw a police
car driving
uphill backwards.
– Hi guys. Why are you driving
backwards?
– Because we are not sure that we will find the place to
make u-turn on
the top of the mountain.
After one hour the same man
saw the same police car driving downhill
backwards again.
– But
guys, why are you driving backwards again?
– We have found the place
to make u-turn up there.
