I love that he gets lazier with the fake names as the week goes on too, starting with the semi-believable "Twig Sigmund" and ending with just "Flipper".
I could also think that some of those pranksters, although intended seemly to be the same caller, may be manifested metamorphosis to put on 'convincing false faces' to fool around. That's kinda scary, especially considering what 'Fred Pinball' initially talks about ...
Just a fair warning, do NOT. UNDER ANY CIRCUMSTANCES, put Flipper (The last one) Under an AI photo enhancer, or you will end up with THIS ABONIMATION that should never see the light of day.
