A heart surgeon came to a mechanic to repair his car. The mechanic had a look at the car's engine, opened a valve and fixed it.
The mechanic said, "I repaired the engine which is the heart of the car. You also operate on the hearts of humans, so our jobs are quite similar. So why it you earn more than me?"
The doctor replied, "Can you repair the car when the ignition is on? We can!"
Professor: "Why do pimples make horrible prisoners?"
Student: "Because they keep breaking out!"
"Stop making a big deal out of it, it's not a big deal."
"Sometimes the smallest things hurt the most."
"How so?"
"Well, you can sit comfortably on a mountain, but you can't on a needle!"
