One day, a shopkeeper put his dumb son in charge of his shop as he had to go out of town .
A customer comes in and asks, "Can I get a Tropicana Orange juice?"
The son searches in the shop for sometime, sways his head and says, "No, we don't have a Tropicana Orange juice."
That night, when the son tells this to his father, he angrily says, "Fool! We had minute maid Orange juice. You should have asked him if he would take it instead of Tropicana."
The shopkeeper puts his son in charge the next day as he had to go out of town once again. Before leaving, he reminds his son of what he had told him the night before.
A lady comes in and asks, "May I have some toilet paper?"
The son searches here and there ,looks up and says, "Sorry, we have run out of toilet paper. However, would you take sandpaper instead?"
