When we think of anti-drug PSAs, the anti-druggiest by far is this little number from not-at-all-crackhead Pee Wee Herman.

In it, Mr. Herman espouses the various dangers of smoking crack rock (with vial in hand) and tries to deter hard-living "Pee Wee's Playhouse" fans from illicit drug use. The word of the day is "No," kids. Just say it. And then we'll all wave our arms and scream. Enjoy!
