A boy
and his father were crossing the road when the boy got knocked
down by a car.The dad rushed the boy to the hospital but
the doctor said "I can't operate on that boy, he's
my son". Yet the father brought him in. Who's the doctor?

A young
boy lived in an apartment on the tenth floor. Everyday,
he takes the elevator down to the ground floor and goes
to school. At three o'clock he comes home and takes the
elevator to the sixth floor then walks the rest of the way.
How come?
Clue:
On a rainy day when he takes his mother's umbrella with
him, he goes straight to the tenth floor.
