Oh, Arghie, I hate to be the one who breaks this to you. It breaks my heart you believe that is whipped cream.
Those are mashed potatoes. Whipped cream wouldn't hold up during the shooting. Gravy, anyone?
Well, whatever it was, I seem to remember there was less of it. (Now that you mention it, I seem to remember having heard that aboot the potatoes or whatever at the time).
