Anyone who remembers the "Newhart" TV show (1982-1990) will remember that Bob Newhart played the owner of a motel in New England, and occasionally, three backwoods brothers would drop by to visit. Only one ever talked, and the words "Hi, I'm Larry, this is my brother Darryl, and this is my other brother Darryl" was their standard introduction. What has this got to do with insulators? Nothing really, but one day I lined up CDs 152, 208 and 213 for a group photograph, and that's who they reminded me of!, since the CD 208 No.44 "crosstop" and the CD 213 No.43 are clearly derivatives of the original CD 152 No.40 "hoopskirt" design. And now, back to our regularly scheduled programming!
