The Ricky & Copper show on WTAE in Pittsburgh - http://en.wikipedia.org/wiki/Ricki_%26_Copper
. My brother got to go on it when he was 5 and I was 3. The stagehands helped keep me (in the audience) quiet by feeding me cupcakes. Then I got to join the kids walking over the bridge at the end of the show.
When I was 5, Mom got me a local taping of Bozo the Clown. They would do regional tapings around the country, not just in Chicago. Krusty the Clown is modeled after Bozo and I can tell you that it's a really accurate portrayal.
We would sneak out of bed when we were slightly older to watch Chiller Theater (http://en.wikipedia.org/wiki/Chiller_Theatre_(Pittsburgh
)), with Bill Cardille as Chilly Billy.
We were also watching the PA lottery drawing the night of the infamous lottery scandal because we used to watch Bowling for Dollars and the drawing came on right afterward.
