Barber and the White Hairs
A bearded man went to a barber shop and said to the master barber: I am bringing home a new wife; I would like you to cut off the white hairs in my beard.
The master took the scissors, cut off the whole beard, put it in front of the man and said: I don't have time. Pick out the white hairs yourself.
