Callers with the Absolute Certitude of the Completely Ignorant. I heard a couple of these tonight as I listened to some of the 16/17 April show.
These are the folks who call in during a discussion of some mysteriously esoteric topic ~ oh, like the building of the Pyramids ~ and pronounce that they-- at long last, THEY-- are going to clue-in the dumb researchers guesting the show, and the rest of the world, because they (the caller) "saw a dokyemintry, and they was a guy sayin' (so and so and so) an' he was a expert!! So, 'at's jis whattAH thank. Whatta y'all thanka that?" (it comes in all accents / dialects; take your pick)
Never mind that there was a guest on "Coast" just last week, and 5 last year, and about 40 since Art went paranormal/esoteric, who detailed that same theory; and another 40 who have mentioned and debunked it. In other words, it's been covered.
BUT NO: this genius who's never heard or read anything else on the topic of the Pyramids (or whatever the topic might be), and probably never even heard "Coast" much, thinks that HE has the answer 'cause HE saw "a expert" --and his "expert" is better than the guest "expert," because HE and ONLY HE saw THAT "expert" first; everything and everyone else in the field be damned, because HE has never heard of them. So he HAS to call in and slow everything down, and probably piss off the guest along with the rest of us, by making them entertain his "contribution."
