From the back of the envelope the booklet comes in: 1) This is not intended for the mentally unstable, for the easily offended, or for persons under 18. Please do not let it fall into their hands. If you think this warning is funny, by all means laugh your ass off, but we're serious. (2) Likewise, if you are mentally unstable, easily offended, or under 18, please do not read the contents until you are older, more experienced, and/or recovered. (3) If you think it would be funny to accidentally' leave the contents of this envelope where they might upset someone, ask yourself: "How funny would it be to have a SWAT team burst through my door and 'accidentally' fire several warning shots into my head and chest?" The booklet comes in a yellow envelope.
