A mechanic was removing a cylinder head from the engine of a Range Rover when he spotted a well-known heart surgeon in the shop. The surgeon was there waiting for the service manager to come take a look at his Mercedes when the mechanic shouted across the garage: "Hey doc, can I ask you a question?"
The surgeon, a bit surprised, walked over to where the mechanic was working on the Range Rover. The mechanic straightened up, wiped his hands on a rag and asked: "So Doc, look at this engine. I open its heart, take the valves out, repair any damage, and then put them back in, and when I finish, it works just like new. So how come I get such a small salary and you get the really big money, when you and I are doing basically the same work?"
The surgeon paused, smiled and leaned over and whispered to the mechanic: "Try doing it with the engine running."
Here's a math question. If you get into bed 9 hours before you have to wake up, and your wife wants to have 2 hours of sex, how much sleep will you get?
Answer: 8 hours, 57 minutes - who cares what she wants!
A woman is in her doctor's office, when she suddenly shouts out, "Doctor, kiss me". The Doctor looks at her and says that it would be against his code of ethics to kiss her.
About 20 minutes later the woman again shouts out "Doctor, please, kiss me just once". Again he refuses, apologetically, but says that as a doctor he simply cannot kiss her.
Finally another 15 minutes pass, and the woman pleads with the doctor, "Doctor, Doctor, please kiss me just once!!"
"Look" he says, "I'm sorry. I just CANNOT kiss you. In fact, I probably shouldn't even be screwing you either."
