You can also check snopes.com but if you use a search engine and can't find a connection between your tinfoil terms then guess what? It probably isn't a real issue. Try to be the peacemaker in your family and just whack your nephew in the head with a cast-iron skillet. That will settle the debate.
Thanks for the tip on snopes.com. I wasn't familiar with them, and have sent them an inquiry. I figure I'll wait till I hear something, and THEN will show it to my nephew shortly before I hit him on the head with a cast iron skillet.
