Cecil Adams rocks!
I love The Straight Dope column in The Chicago Reader. Column writer Cecil Adams manages to get to the truth about *anything* with acerbic wit. He's been writing for over 25 years, and here's a column you can read as a sample: Do tinfoil helmets provide adequate protection against mind control rays?
There's dozens of his columns online for you to enjoy...but buy one of his Straight Dope books too!
