An Irishman went to London for a visit to the zoo. While there, he saw a man with an elephant act. The man claimed the elephant could look at person and tell that person's age.

The Irishman was very skeptical and said so, in no uncertain terms. The man
had the elephant look at a small boy and the elephant stamped its foot 9 times. "Is that right?" he asked the boy.

"Oh yes." the boy said.

The Irishman was very loud, in his not believing that this was true. The man asked the elephant to tell the ages of several people, and each time the elephant stamped his foot and the people said he was correct.

The Irishman got even louder and more abusive toward the man.
Finally the man could take it no longer and wagered the Irishman that the elephant could look at him and tell him his age. The Irishman took him up on the wager. The elephant looked real close at the Irishman, turned around, raised his tail and cut wind like you wouldn't believe, turned back around and stomped his foot twice.

Whereupon the Irishman stumbled back and with a sound of disbelief in his voice cried, "BeGabbers, he's right! Farty-two!"
