Hah, you know the gas masks the military uses? We had an exercise one day in New Mexico, had to wear those damn things for *hours* in the desert heat. They have a little nozzle/tube thing on them that attaches to your canteen so you can drink water, theoretically even while you're in the middle of a cloud of nerve gas or whatever. Well, I crammed a joint into the nozzle, and I was able to get high without taking off my mask. I just let the joint dangle down my chest from the drinking tube while I toked on it, walked around and showed my compadres my mask full of pot smoke and my incredibly bloodshot eyes. Good times!
