Ever notice how in many TV shows, whenever a nudie magazine is needed for a scene, more often than not you see the same copy of the fictional "Playpen" magazine being used as a prop? The mag's name appears in blue, using the same font as Playboy's, and the cover has a picture of a blonde, bikini-clad woman against a black background. Does anyone know if this is some sort of gigantic showbiz running gag? I've spotted it in everything from "Married with Children" to "Friends" to "Wings" to "Home Improvement", and several others, and I've always wondered why shows produced by different companies and aired by different networks, would use the same prop. Yes, meaningless question, but that's what the internet is for, right?
