I believe Penn & Teller made a reference to the Dope in this episode, during the trick with the spike tape.
Watch when Penn pages through the sample book. On “Page 14”, when Penn points out “Davidfield Copper”, look five down. It’s misspelled, but it says “Staight Taupe”.
What do you think? I could easily believe Penn, and / or Teller have been Straight Dope readers at some point.
(I have a screen shot, but this is my first post in many months and I don’t see how to include it. I tried, but the system said no.)
