Oh, yeah. Mad had a number of pull out "45's", some of which were positively brilliant. I specifically recall the All in the Family parody issue, complete with a plastic sheet 45 record - "Gall in the Family Fare". The Archie Bunker impression was great and precient.. "They ain't laughin' at me... they're laughin' wit' me..."
That got me in SO much trouble when I slipped it in the middle of a stack of my mom's Hawaiian records ...
Rest in Potrzebie, Al ... thanks for the laughs (and the education)!
