I remember seeing a TV show on Nickelodeon in a motel room back in
1998 that featured a girl sitting on a bed, complaining about a bunch
of stuff. Every so often she would get really excited and started
jumping around on the bed. I think this was the whole show. It was so
weird, I just had to watch. I'm just wondering, what was the name of
this show.

There was a recurring Saturday Night Live sketch in which Lorraine
Newman played a child-like character in her bedroom who would go nuts
and jump on the bed.

There is also a show on Nick called "The Amanda Show" (aka "Amanda
Please")where a quirky little girl named Penelope sometimes throws a
fit on the bed.

Finally there is a show called "The Big Comfy Couch" in which a
child-like character named Loonette sits on a huge couch and
occassionally jumps around in a spastic manner.

Let me know if one of these might be the show you remember.

Just a bit of info:

According to TV.com The Amanda Show did not first air until 11/6/1999

Just thought we could eliminate that one!

Good Luck.

That's true, and the Saturday Night Live sketch was long before 1998,
but I just thought these might be longshots.

FYI...tutuzdad, you're thinking of *Gilda Radner* doing the "Judy
Miller Show" on SNL in the 70's.

:)

Yes, that's the one. My mistake. I did get a good laugh just thinking
about it again. Thanks.
