Probably an oldy too, but...
Scientists should always have a mistress. That way when he's at the lab the women think he's with the other gal.

An architect, an artist, and an engineer were discussing whether it was better to spend time with the wife or a mistress.
The architect said he enjoyed time with his wife, building a solid foundation for an enduring relationship.
The artist said he enjoyed time with his mistress, because of the passion and mystery he found there. The engineer said, "I like both."
"Both?" asked the architect and artist in unison.
The engineer replied, "Yeah. If you have a wife and a mistress, they will each assume that you are spending time with the other woman, so you can go to the office and get some work done."
A man is flying in a hot air balloon and realizes he is lost. He reduces height and spots a man down below. He lowers the balloon further and shouts, "Excuse me, can you tell me where I am?"
The man below said, "Yes, you're in a hot air balloon, hovering 30 feet above this field."
"You must be an engineer," said the balloonist.
"I am," replied the man. "How did you know?"
"Well," said the balloonist, "everything you have told me is technically correct, but it's of absolutely no use to anyone."
The man below said, "You must be in management."
"I am," replied the balloonist, "but how did you know?"
"Well," said the man, "you don't know where you are, or where you're going, but you expect me to be able to help. You're in the same position you were before we met, but now it's my fault."
There was an engineer who had an exceptional gift for fixing all things mechanical. After serving his company loyally for over 30 years, he happily retired. Several years later the company contacted him regarding a seemingly impossible problem they were having with one of their multi-million-dollar machines.
They had tried everything and everyone else to get the machine fixed, but to no avail. In desperation, they called on the retired engineer who had solved so many of their problems in the past.
The engineer reluctantly took the challenge. He spent a day studying the huge machine. At the end of the day, he marked a small "x" in chalk on a particular component of the machine and proudly stated, "This is where your problem is." The part was replaced and the machine worked perfectly again.
The company received a bill for $50,000 from the engineer for his service. They demanded an itemized accounting of his charges.
The engineer responded briefly:
One chalk mark ................. $1
Knowing where to put it ... $49,999
