An 70-year-old married a 20-year-old. A year after the wedding the couple arrives at the delivery room. A male boy weighing 3.5 kg was born, healthy and beautiful. The nurse asks the old man "Yours?" "Yes," the old man replies proudly. "Congratulations," the nurse replies. "Well..." says the old man, "the old engine still runs!" Two years later the duo arrives at the delivery room again. A 3.5 kg girl was born, healthy and beautiful. The nurse asks the old man: "Yours?". "Yes" the old man answers. "Well done" the nurse answers. "The engine still runs!" said the old man. After two more years, they come to the delivery room again. A 3.5-year-old male son is born, healthy and beautiful. The nurse asks the old man: "Yours?". "Yes," the old man replies. "Congratulations," the nurse says, "that's really impressive." "Well..." says the old man, "the engine is STILL running!" "Well... says the nurse, "you may want to change the oil, the last one came out black."

A man is lying in the hospital, waiting to be the first person in history to receive a brain transplant. A doctor comes in and says "Congratulations! But unfortunately since this is a new procedure your insurance isn't going to cover it all. So we're going to give you 3 choices for brains and you can decide which you can afford." "Okay, what are they?" Says the man to the doctor. The doctor says "Well, first there's engineer brain, that's $100 an ounce. Then there's astrophysicist brain, that'll cost you $200 an ounce. Finally there's politician brain. That's the most expensive at $1000 an ounce." The man looks at the doctor, surprised. "That's absurd! Why is the politician brain so expensive?" The doctor turns to him and says "Sir, do you have any idea how MANY politicians it takes to get an ounce of brain?!?"
