I was allowed to read/buy Mad comics only in convenience-store book-rack paperback digests, because Mom felt the magazine was too trashy as a whole.
The joke was on her. No one was thriftier, or more eager for her children to learn more about the world. Instead she paid far more for much less. All randomly out-of-date too, with jokes about Adlai Stevenson two decades after he had run for president.
