Gifts on the first day of school joke

On the first day of school, the children brought gifts for their teacher. The florist's son brought the teacher a bouquet of flowers. The candy-store owner's daughter gave the teacher a pretty box of candy. Then the liquor-store owner's son brought up a big, heavy box. The teacher lifted it up and noticed that it was leaking a little bit. She touched a drop of the liquid with her finger and tasted it.

 "Is it wine?" she guessed.

 "No," the boy replied. She tasted another drop and asked, " Champagne ?

 "No," said the little boy... "It's a puppy!"
