Foam at the mouth and fall over backwards. Is he foaming at the mouth to fall over backwards or falling over backwards to foam at the mouth. Tonight 'Spectrum' examines the whole question of frothing and falling, coughing and calling, screaming and bawling, walling and stalling, galling and mauling, palling and hauling, trawling and squalling and zalling. Zalling? Is there a word zalling? If there is what does it mean...if there isn't what does it mean? Perhaps both. Maybe neither. What do I mean by the word mean? What do I mean by the word word, what do I mean by what do I mean, what do I mean by do, and what do I do by mean? What do I do by do by do and what do I do by wasting your time like this? Goodnight.
