Outside of Treehouse and the youth channels, Growing up especially when I was a teen, I loved the Canadian sit com Corner Gas. I got into it through the amusing bumpers Ctv would put out before each episode. They featured a unique song really only ever used in the bumpers and in some special features in the dvd releases and the Ctv announcer guy was a lot of fun as well. Sadly, most of these are lost. I know it's an odd request but these little commercials are really nostalgic to me as they got me into one of my favorite shows. It was my favorite show for a long time only ever surpassed by Gravity Falls some years later. I would really love to see these again. There are a few on youtube vhs rips. I asked the guy if he had anymore but he never replied back.
I remember the one for the episode "Rock Stars" in which the announcer said "Hank's pumpin' up!" or something like that. I know just little commercials but Corner Gas was/is such a big show for me it helped me develop my style of humor in my own works so these are kind of important to me.
