a device used for the smoking of tobacco. not only is the pipe the best method for tobacco consumption, it serves as a magical bond between all pipe smokers past and present. the pipe allows the smoker to summon any of the powers held by other pipe smokers, like the intelligence of Albert Einstein. pipes also smell and taste great, are a great way to relax, and are irresistible to women.
