A gynecologist was getting sick of his job and decided he needed a career change. He had always enjoyed tinkering with engines, so he decided to become a mechanic. He went to mechanic's school and excelled in his studies. Finally, it came time to graduate, but he had to take an engine apart and then reassemble it in perfect working order. Our intrepid friend did the test and anxiously awaited the results. Two days later, he got his score and almost passed out. He had recieved a 150% score! He called his instructor to find out about the amazing score, could this be a joke? "No, no, that's right, 150% was your score. I gave you 50% for stripping down the engine, a very thorough job. I gave you another 50% for reassembling it, a fantastic job. I also gave you an extra 50% for doing it through the muffler!

Maybe he was suffering from "tunnel vision"?

Lately I think my job has changed from sales to urologist. It seems that a majority of the customers are pricks.

Proctologist, more likely, arseholes...
