Teachers Pet?

It was the end of the school year, and the infant school teacher was receiving gifts from her pupils.
The florist's son handed her a long box, and she said "I bet I know what it is. Some flowers?"

"Right," said the boy. "How did you know?"

"Just a wild guess," she said.

The daughter of the owner of a sweet shop produced a gift. The teacher shook it, and said, "I bet I know what this is. A box of sweets?"

"That's right," said the girl, "but how did you know?"

"It was a lucky guess," said the teacher.

The next gift came from a boy whose father owned the off licence.
The teacher held the package overhead -- and noticed it was leaking. She touched a drop with her finger, put it on her tongue, and asked the boy: "Is it wine?"

"No," the boy replied.

The teacher took up a larger drop and said, "Is it champagne?"

"No," said the boy, with great excitement. The teacher sipped one more drop, and declared, "I give up. What is it?"

"It's a puppy!!!"
