BERR-WYN!

Is that a 90s Chicago talk radio reference? (I think it is?)

Svengoolie, if I remember right.

Also known as Son of Svengoolie. The original Svengoolie retired in the 70s. I don't recall BERWIN being a bit back then (though that was terribly long ago).

I suspect, though I have no proof, that he at least partially inspired the Joe Flaherty SCTV character Count Floyd/Floyd Robinson.

Actually, Rick Koz is the original and current Son of Svengoolie character. He's been on two or three different stations since the 70's I think, but it's the same guy.

Jerry Bishop played the character in its original run. Way up on channel 32. Wiki says 1970-1973.

Jerry Bishop (the original Svengoolie) started the BERWYN gag.

Oh, wow, I had no idea. Glad I asked.
