Tom Wells said:Some 40 years ago, Jerry G Bishop developed the Svengoolie character, and "Berwyn" became a similar reference in the
Chicago area. It is still used in the modern Svengoolie show, and often, here the region, when someone mentions Berwyn in conversation, another person will chime in with the comedic, extended " Berrr--wyyn!?"
Which was literally "borrowed" from Cleveland's "Ghoulardi"..Jerry G. was at KYW Radio 1100 and TV-3 in Cleveland during Ghoulardi's heyday..Ernie Anderson (Ghoulardi) lived in the Cleveland suburb of Parma early in his Cleveland radio career..Director-Engineer Chuck Schodowski bought a house in Parma...Anderson could'nt resist cracking jokes about Paaar--ma?..An extension of this would be jokes about Parmaites wearing white socks and having pink flamingos on their lawns..So, in general, "Svengoolie" began as a takeoff on "Ghoulardi"
