"Adam Corolla once said on his radio show that the female reproductive system is like a porsche; it's a high-performance thing of beauty and a lot of fun to drive, but they need a lot of regular maintenance and spend a lot of time in the shop.

Where as male genetalia is more like a 77 subaru wagon: all you have to do is change the oil, keep the tires inflated and it will run a million miles. Any repairs that it may need you can do yourself with pliers and baling wire."
