The Summoner creators didnt come up with it. Its a take off of the old Dead Ale Wives skit. Its been around for more years than I can remember. It actually mentions the Dead Alewives on the download page you have the link to. I think it came out in the 80's when all the groups got up in arms about D&D being a game for the devil worshippers and pagans. Was a bunch of crap. The skit is kinda funny though.
It is best to be thought a fool and stay silent, than to open your mouth and remove all doubt.
