They are like this too

I enjoy reading Straight Dope sometimes. Today's mailer brought back recollections of an old quizzing chestnut about a cigarette tax or something.(Churchill was involved in some way I think) Shame is, I can't remember it! If someone could please refresh my memory in the comments that would be great.

Anyway - what reminded me of that question was this : How Come We never see Class B cigarettes. Any article that has the words "Federal Bureau of Alcohol, Tobacco and Firearms" deserves special attention!
