how to achieve 50 years

A couple was celebrating their golden wedding anniversary. Their
domestic tranquility had long been the talk of the town.

A local newspaper reporter was inquiring as to the secret of
their long and happy marriage.

“Well, it dates back to our honeymoon,” explained the lady. “We
visited the Grand Canyon and took a trip down to the bottom of
the canyon by pack mule. We hadn’t gone too far when my husband’s
mule stumbled.

My husband quietly said ‘That’s once.’

We proceeded a little farther when the mule stumbled again.

Once more my husband quietly said, ‘That’s twice.’

We hadn’t gone a half-mile when the mule stumbled a third time.
My husband took a pistol from his pocket and shot him.

I started to protest over his treatment of the mule when he
looked at me and quietly said… ‘That’s once.'”
