I don’t use drugs, but I do like honest reactions to things. You have to watch this video to the end.
Ok, looks like YouTube pulled it, but it was a guy demonstrating that you lose the will to drive your car when you smoke some drug. He sits in the driver’s seat, placid, the car unmoving. And then, his expression changes and he flails his arms a bit and makes a sound of being stunned, and the camera turns to reveal that a cat has just sat upon the windshield (prompting his instinctual reaction). It was a good clip.
