An older, white haired man walked into a jewellry store one Friday evening with a beautiful young gal at his side.

He told the jeweller he was looking for a special ring for his girlfriend. The jeweller looked through his stock and brought out a $5,000 ring. The old man said, "No, I'd like to see something more special."

At that statement, the jeweller went to his special stock and  brought another ring over. "Here's a stunning ring at only $40,000" the jeweller said.

The young lady's eyes sparkled and her whole body trembled with excitement. The old man seeing this said, "We'll take it."
The jeweller asked how payment would be made and the old man stated, "by cheque. I know you need to make sure my cheque is good, so I'll write it now and you can call the bank Monday to verify the  funds and I'll pick the ring up Monday afternoon," he said.
Monday morning, the jeweller phoned the old man.  "There's no money in that account."
"I know," said the old man, "But let me tell you about my weekend!"
