Well I'm not really sure how safe they'll keep you from serious bio-hazards, but they've got to be better than just pulling your shirt up over your nose, right? Maybe not, I don't know. I ain't no damn noseologist, I'm a geekologist. Anyway, the Nose Mask Pit cost $14 and fit nice and tight up in your nostrils to keep out allergens and other nasty stuff. Maybe you want them, or maybe you prefer a surgical mask. Personally, I don a full-fledged gasmask. Like my grandpappy used to say, you never can be too safe or too drunk at a seedy strip club. Amen to that, pappy. If you do decide to go with these, let me give you a word of warning: Be careful. As a kid I stuffed two Hot-Wheels tires up one nostril and a cherry pit up the other and had to go to the hospital. My mom was afraid they'd cause lasting damage, but, thankfully, the doctor assured her I was retarded long before the incident.
