It was at the end of the school year, and a
kindergarten teacher was receiving gifts from her
pupils. The florist's son handed her a gift. She
shook it, held it overhead, and said, "I bet I
know what it is. Some flowers." "That's right"
the boy said, "but how did you know?" "Oh, just
a wild guess," she said. 

The next pupil was the
candy shop owner's daughter. The teacher held her
gift overhead, shook it, and said, "I bet I can
guess what it is. A box of sweets." "That's
right, but how did you know?" asked the girl.
"Oh, just a wild guess," said the teacher. The
next gift was from the son of the liquor store
owner. The teacher held the package overhead, but
it was leaking. She touched a drop of the leakage
with her finger and touched it to her tongue. "Is
it wine?" she asked. "No," the boy replied,
with some excitement. The teacher repeated the
process, taking a larger drop of the leakage to
her tongue. "Is it champagne?" she asked.
"No," the boy replied, with more excitement. The
teacher took one more taste before declaring, "I
give up, what is it?" With great glee, the boy
replied, "It's a puppy!"
