Grandpa was celebrating his 100th birthday and everybody complimented him on how athletic and well-preserved he appeared.
"Gentlemen, I will tell you the secret of my success," he cackled. "I have been in the open air day after day for some 75 years now."
The celebrants were impressed and asked how he managed to keep up his rigorous fitness regime.
"Well, you see my wife and I were married 75 years ago. On our wedding night, we made a solemn pledge. Whenever we had a fight, the one who was proved wrong would go outside and take a walk."
After he left, he double-checked it on his calculator... he knew he had screwed up and wouldn't get the job.
But then, two weeks later, he got a letter that said he was being hired for the job! He was not one to look a gift horse in the mouth, but was still very curious. The next day he went in and asked why he got the job, even though he got such a simple question wrong.
The boss shrugged his shoulders and said, "Well... you were the closest."
