Johnny & the bus driver
The first day of school, Johnny gets on the bus, remembering what his father told him, says to the bus driver, "Doog moaning buth driber,"
The bus driver slaps him in the mouth, and sends him to the back of the bus.
This goes on for four days.
Finally, Johnny tells his father the problem, "Fatter you tell me to be pollite, but when I do the buth driber shlaps my in ma faith."
His father says, "Tomorrow I will wait at the bus with you."
The next day, there they are waiting for the bus. When it arrives Johnny’s father says, "Go on Johnny get on the bus and be polite."
Johnny does but looks to his father with fear in his eyes.
His father says, "Go on Johnny."
So Johnny, wanting to be as polite as possible says, "Doog moaning buth driber."
With that the bus driver raises his hand in an attempt to strike Johnny in the face, but before he can Johnny father grabs the drivers hand.
He asks, "Why do you smack my son, when all he is doing is being polite?"
The bus driver says, "Betause heeth making fun of me"
