"He recalled the time when MAD was banned from Oklahoma for being communistic. The magazine had to go to court after being placed on what was called the state "smutmobile" by the state's attorney general. Gaines said the attorney general was said to be a friend of an Army general in Europe who "got up in front of a group of people and told them we were tainted with Communism." The state government put MAD in the same category as all of the dirty magazines of the day. Gaines had to sue to get back on the newstands."
