As a cunning man Gypsy stumped

Standing at the station, and nearby, modestly leaning against a wall, is not a measure of screwy man. An intelligent appearance, is seen on the train had a little too much. And then it taxis to the Gypsy:

— Darling, please help the donations. Will tell you anything you want...

The man hesitantly pulled out his wallet, and from there retrieves the coin, and then abruptly turns around and asks an unexpected question:

— Tell me about the half-life of radium!

Gypsy's face changed, and opened his eyes.

— Here you see! And you said tell you! Does not work! — with these words he returns the note back in the wallet and is removed away.

In my opinion, the perfect excuse.
