Uri Geller
Is an astute feller.
However often he is debunked,
He knows his career will never be defunct.

Hannibal the Carthaginian
Used elephants to expand his dominion.
His exploits were full of drama,
Until he was defeated at Zama.

Hennig Brand
Was an alchemist who tried his hand
At making gold from urine or whatever;
His discovery of phosphorus was more lucky than clever.
