I loved MAD magazine and read it between 7th and 10th grades in the mid to late '60's. I was an aspiring artist and drew caricatures of classmates and family, so I especially loved the parodies of TV shows and movies they had, and my favorite caricature artist at MAD magazine was Mort Drucker

)

As I was Google-searching, I came across this link for "Mad Mumblings" for MAD Magazine fans that some might be interested in:

There was a bookstore/newsstand in our town where I used to buy my MAD magazines. I'd mosey in after school to buy a MAD, along with some candy from the counter and, until it was sold a while ago and turned into a women's clothing boutique, over the years, I loved going into that store and breathing in the musty smell of newspapers, magazines, and paperbacks. I was always immediately transported back to junior high school and simpler times whenever I got a deep whiff!
