She insisted she wanted to speak with the president of the National Bank in order to open an account, saying "a lot of money" was to be dealt with.
After some hesitation, the staff escorted the elderly woman to the president's office. The president asked how much money she wished to deposit in the bank.
'$165,000' she answered, and poured the bank notes from her bag on the table.
Obviously, the president got really curious about the origin of all this money, so he asked where the cash came from.
'Gambling' she muttered.
'What kind of gambling?' the president asked.
'Bets. Let me give you a real example. I'll bet you $25,000 that your balls are rectangular.'
'Hahaha. That's a stupid bet. You could never win.'
'Would you care to accept the bet, then?' asked the elderly woman in a challenging tone.
'Of course! I'll bet $25,000 that my balls aren't rectangular!'
'Since it's such a large sum, would it be possible for me to return tomorrow morning with my attorney as our witness?'
'Sure' said the president of the bank in an extremely satisfied tone.
That night, the president actually got scared because of the bet.
He spent quite some time in front of the mirror, checking his balls, turning them to the left, to the right, and to the left again.
He meticulously inspected them to make 100% sure his balls weren't rectangular so he could win the bet.
The next morning, the elderly woman entered the president's office with her lawyer. She introduced the latter to the president and repeated the bet.
'So $25,000 that the president's balls are rectangular!'
The president accepted the bet once again, then the little old woman asked him to lower his pants so they could all see his balls. The president complied.
The elderly woman inspected his balls really closely, then inquired whether she could touch them, which the president accepted... after all, he had the opportunity to win $25,000!
That's when he noticed the woman's lawyer started to bang his head against the wall.
'What's the problem with your attorney, m'am?'
'Oh, nothing. Only that yesterday I bet him $100,000 that today I'd hold the president of the Canadian National Bank's balls in my hand.'
