The sad thing for me is that, except for the first one, I remember all of those commercials. Man I'm getting old.
In the 1971 commercial Ed says "You notice, at Pizza Hut they put the sauce on with a ladle and not a paint brush." Well, when did they stop doing this? For years now, any time that I've had Pizza Hut pizza, there was very little sauce, as if it were painted on. I always liked their sauce...back when you could taste it.
