My house always had the latest issue of MAD (and usually Cracked) when I was growing up -- and I wasn't the one who bought them. My mother was a huge fan! The fold-out always amazed me. How he could come up with the concept, first of all... then arrange it and make it work, it was like magic.
She also had books of Spy vs Spy (and another by Antonio Prohias), a couple of Snappy Answers, one or two by Don Martin, and several Dave Berg Looks At.
Between those and the Monty Python books she bought, I ended up a little twisted.
