the gas is nice...nothing better then a full tank..//content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif Its even fun at the dentist, though not as much fun as having your own tank. Some dentist will give you a sedative hypnotic like halcion or valium. Either way its ok with me //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifIll stick to the green, im already fat, i dont wanna have to get swollen, never tried gas tho
