while actually drinking gasoline makes you stupid, i am a firm believer that if you accidentally get it on your hands when pumping gas, you can smell them all night and it might make you smarter.
i came to this conclusion after getting gas on my hands today at the pump. if you google “smelling hands” this is one of the pics that comes up. i wish i was famous enough to have my picture pop up when people google a random, yet exact action.
