Hey, I Remember This Show: The Alvin Show (1961)

Wow! Alvin and the Chipmunks have been around since 1961. I had no idea that such a great contribution to Western culture happened during the year of my birth.

On a more serious note, it should be pointed out that the tall guy with the moustache who keeps interrupting the action in this intro is cartoon character Clyde Crashcup, a would-be scientific genius who was often kept a hair's length away from disaster by his short and bald assistant Leonardo. He used to appear quite regularly on the original Alvin Show but since then, he has disappeared into cartoon oblivion -- unless you wish to regard that short, moustached guy who was regularly pestered by the Pink Panther as one of his distant descendants.

Hey, I Don't Remember This Show: Alvin and the Chipmunks (1983)

Apparently there was an attempt to reboot the original Alvin and the Chipmunks series of the 1960s back in the 1980s that I don't recall. As much I loved the original Chipmunks show, I somehow doubt I was missing much by not seeing this version. Of course, YMMV.
