When my son was a toddler, he would watch this show over, and over, and over, and over again on Nick Jr. or Noggin, can't remember which channel. I would cringe when I heard the theme music then put on a huge fake smile, sit on the floor with him, and play along. They never made any new episodes it seemed like so we watched the same episodes until my brain was pretty much tapioca pudding. The show came on it seemed like ten times a day and he ALWAYS wanted to watch it if we were at home.
Later on I would catch myself humming the damn music if we got really busy in the 911 dispatch center, complete with the dog "ruff, ruff" sound effects, some kind of weird stress coping mechanism I guess. Got some weird looks from my co-workers..except the ones with kids the same age as mine, they got it...lol
