To cheer you up (or, alternatively, make you definitely decide to leave the planet for good), watch this vaccine promotional video: Sid the Science Kid gets a Flu Shot. Enjoy!
Hi, my name is Paul, and I work in a button factory. I've got a wife and two kids. Then one day my boss came to me and said "Are you busy Paul??" I said "NO." "So push this button with your left hand." So I did. And the process repeated itself over and over until all my body parts were pushing buttons. It was completely ridiculous...so I quit!
