Tenth Planet?

Didn't we learn anything from Gordon Shumway?

I thought Alf taught us that the next two planets out after Pluto were going to be called "Alvin" and "Dave."

(Hello: It's possible I am misremembering my late 80's, Monday Night, NBC Prime Time Television Programs, but I seem to remember the kid on Alf coming home and yelling at our favorite alien after proposing at a science fair that the tenth and eleventh planets were named after Chipmunks characters)

But "scientists" are calling a planetoid thing orbiting our sun a few billion miles out "Sedna," after the Inuit goddess of the sea. Oh. OK, then.
