Uncle John Probably Reads Cecil Adams

Uncle John's Bathroom Reader
Uncle John’s Bathroom Reader:

Since 1988, the Bathroom Readers’ Institute has led the movement to stand up for those who sit down and read in the bathroom.
So, you ask: what is a Bathroom Reader? Simply put, we keep you occupied in the john. No more mad dashes for the perfect reading material — our books have it all!

We have one of their books, which are simply full of trivia, as shown in their Throne room.

I prefer Cecil Adams’ Straight Dope books for bathroom reading.
