Someone bought this for the kid. I'm absolutely amazed by how much fun and enjoyment we are getting out of it. We're not in grade school, but we had a laugh riot. We even had contests to see who could make the best one. What's even more amazing is the number of speciality stores I found selling stuff like like this.
My mother once gave me a book of limericks and poems on the subject. But, if you want to really be informed about the source of the subject, hold your breath before going here.
