It's been 20 years since Baby Sinclair first uttered the words "Not the mama!"

Yep, it's OK to feel old now.

On April 26, 1991, the world was introduced to the Sinclair family on ABC's 'Dinosaurs.' The sitcom lasted for four seasons and 65 episodes (58 episodes aired during the first run; the remaining aired in syndication) before ultimately ending with the extinction of dinosaurs. (Inevitable, we suppose.)

While 'Dinosaurs' was a sitcom, the show broke the mold by not having a studio audience or a laugh track. Brought to life by a cast of experienced Henson puppeteers and seasoned voice actors, 'Dinosaurs' is heralded as one of the most ambitious sitcoms ever.

Celebrate the 20th anniversary of the premiere of 'Dinosaurs' with a walk down memory lane after the jump.

(S14E05) No one, but no one, takes on obnoxious celebrity behavior with more gleeful scorn than 'South Park.' They've taken on everyone from presidents to b-movie actors and the world's biggest rock stars, and most every time, they have been right on target. It's what has made 'South Park' beloved to audiences and drawn the ire of the celebrities themselves.

So to celebrate episode 200th of the show (called '200'), show creators Matt Stone and 'Trey Parker decided to bring back every celebrity they have ever made fun of and take them on all at once (see the incomplete list of those appearing on the show below). The result is a bizarre episode, even by 'South Park' standards (if you still have it on DVR, there are a few plot spoilers ahead).

(S07E15) Perhaps Emily Gilmore should drink more often.

That's the take-away I get from this episode. When Emily drinks, she's warm and open, and almost forgiving of her "wayward" daughter Lorelai. When she doesn't drink, she's prickly, mean, and prone to judge everything and anything, including how her daughter is managing her life.

If I were Lorelai and I had the choice, I think I'd take drunk Emily any day of the week. And I think Lor realized that as she walked out of the Gilmore family dining room at the end of this episode.

(S07E13) So this is what it takes to get a good episode this season? Richard Gilmore has to have open-heart surgery? Well, I guess if this is what they have to do, I can accept that. Maybe next week, they'll give Paul Anka worms.

Seriously, though, the reason why this episode worked is because all we saw was the Family Gilmore, together for most of the episode. Not sixty seconds of a Friday night dinner. Not Lorelai and Rory chatting on the phone. Nope, they were all together for an extended period, interacting in the ways that once made the show so great.

Did this episode have flaws? Tons. But it was the best of the season so far.

You'll remember Evans from his role as Lionel Jefferson on All In The Family and the spinoff show The Jeffersons. He died of throat cancer last week in California.

Besides his role as Lionel, Evans also appeared in The Streets of San Francisco, Rich Man, Poor Man, Love, American Style, Match Game, and Walker, Texas Ranger. He was also one of the creators and writers of the sitcom Good Times.

I had forgotten this, but he was actually replaced as Lionel Jefferson on The Jeffersons for four years, in the late 70s. He was replaced by Damon Evans, then returned to the show for the last couple of years.

(S07E09) This one felt cozy, didn't it? Snappy dialogue, funny situations (I mean, come on... huge knitting needles and balls of yarn?), quirky parties, story development... This week's episode felt almost... almost like the Gilmore Girls we knew and loved, moreso than any we've seen this year so far. One problem, though:

Christopher.

How is he gumming up the works so much, literally, figuratively, and everything in between? It's not like the town never knew he existed up until now; he's been in and out of Lor and Rory's life for over 20 years. Surely, the folks in Stars Hollow would be treating him more warmly in the past than they are now, when he's Mr. Lorelai Gilmore. There's just one thing that can explain this: Sloppiness.
