A gynecologist has a midlife crisis and takes night classes to become a mechanic...

She's really nervous the night of the final, so she studies real hard and hopes for the best. When the grades are posted, she freaks out because her grade says 150% and she assumes it was an error, so she goes to see the instructor. He explains it's no error. "You took apart the engine perfectly, every nut, every bolt. You pulled it all apart without breaking anything. That got you 50% Then you put it all back together perfectly. It actually ran better than before you started, so I gave you 50% for that. You got a bonus 50% for doing it all through the muffler."
