A little old lady walks into the Bank of Canada with a bag of money. She insists that she must speak with the president of the bank.

 

She tells the bank president that she has accumulated several hundred thousand dollars over the years and would like to open a trust in the bank.

 

The president is curious, so he asks her, “Where did you get all this money?” The old lady replies, “I make bets.”

 

The president then asks, “Bets? What kind of bets?”

 

The old woman says, “Well, for example, I’ll bet you $25,000 that your balls are square.”

 

“Ha!” laughs the president, “That’s ridiculous — you can never win that kind of bet!”

 

The old lady challenges, “So, would you like to take my bet?”

 

“Sure,” says the president, “I’ll bet $25,000 that my balls are not square!”
