My grandmother went into the Bank of Nigeria one day carrying a bag of money.

She insisted that she must absolutely speak with the president of the bank to open a savings account because, "It's a lot of money!"

After much hemming and hawing, the bank staff finally ushered her into the president's office (the customer is always right).

The bank president then asked her how much she would like to deposit.

She replied "1 million Naira" and dumped the cash out of her bag onto his desk.

The president was of curious as to how she got the money, so he asked her, "Ma'am, I'm surprised you're carrying this much money around. Where did you get this money?"

My grandmother replied, "I make bets."

The bank president then asked, "Bets!? What kind of bets?

My grandmother said, "Well, for example, I'll bet you 25,000 Naira that your balls are square."

"Ha!" laughed the president. "That's a stupid bet. You can never win that kind of bet!"

My grandmother challenged, "So, would you like to take my bet?"

"Sure", replied the president, "I'll bet you 25,000 Naira that my balls are not square!"

My grandmother then said, "Okay, but since there is a lot of money involved, may I bring my lawyer with me tommorrow at 10:00am as a witness?

"Sure!" replied the confident president.

That night, the president got very nervous about the bet and spent a long time in front of the mirror checking his balls. Turning from side to side, again and again. He thorougly checked them out until he was sure there was absolutely no way his balls were square and that he would win the bet.

The next morning, at precisely 10:00am my grandmother appeared with her lawyer at the president's office. She introduced the lawyer to the president and repeated the bet: "25,000 Naira says the president's balls are square!"

The president agreed with the bet again and the old lady asked him to drop his pants so they could all see.

The president did.

My grandmother peered closely at his balls and then asked if she could feel them.

"Well, okay," said the president, "25,000 Naira is a lot of money, so I guess you should be absolutely sure".

Just then, he noticed the lawyer was quietly banging his head against the wall.

The president asked the my grandmother, "What the hell is the matter with your lawyer?"

She replied, "Nothing, except I bet him 100,000 Naira that at 10:00am, I'd have the Bank of Nigeria's president's balls in my hand."
