This is Dan.

Doesn't he look young, pure, and innocent in this picture?

In high school Dan was a good boy. He did his homework, he shined his shoes, he ate his vegetables, and did as he was told. But one day he went away to college. Dan fell in with a bad crowd. He stopped shining his shoes. He started eating strange things. He smoked dope. His head became filled with left-wing ideas. He took drugs. He stopped going to the barber. And after four years, Dan didn't graduate, but he looked very different. He looked like this. (click the picture.)
