In TV, there are two distinct worlds: our world and the cartoon world. So far, we've gotten along pretty well because, for the most part, cartoons have kept their animated butts in their world.

We don't allow it to happen very often because when cartoons try to invade the real world on those rare occasions, the transference is nightmarish. Their distorted animated features and expressions can make 'Eraserhead' look like an Olson Twins movie.

Here are five of the creepiest looking and sounding real life cartoon crossovers that will have you bleaching your brain with the magic of Clorox 2.

Lost fanatics, rejoice! We may still have, oh, more than half a year left before we get cheerfully dumped with a load of new episodes (::drool::), but in the meantime, we have DVD's, abc.com, repeats on SyFy, and YouTube!

Yes, YouTube.

Well, technically, we can't get our fix of full episodes on "the Tubez," but the site still provides us with plenty of fodder; fan dedications, clip montages, and music videos galore. Let's face it: people love their Hurley birds, smoke monsters, and everlasting, cancer-conquering romances. And why shouldn't they?

The Zack Attack is back! Alas, it was for one night only.

Last night, Mark-Paul Gosselaar surprised Jimmy Fallon on 'Late Night' by showing up dressed as Zack Morris from 'Saved By the Bell' -- complete with giant mobile phone. Fallon's been obsessed with putting together a 'Saved By the Bell' reunion, and Gosselaar (who now stars in TNT's 'Raising the Bar') gamely agreed to participate -- if Fallon can get everybody else on board.

It got us thinking about which of our favorite '90s sitcoms need to hold reunions, like, yesterday. 'The Today Show' already hosted a 'Cosby Show' reunion, but here are some more meet-back-ups we really, really want to see:

(S03E02) From the title, it was clear tonight's show was going to relate to Ferris Bueller's Day Off. In fact, in true Shawn and Gus fashion, the entire John Hughes' oeuvre was mined for comic gold, as Gus was hosting the 13th high school reunion -- that's right. Not 10, but 13 years. Ironically, in 1995 there was no John Hughes movie. Never mind, the references were more '80s than '90s anyway, including Milo and Otis, Karla DeVito, and all those Hughes movies.

Overall, there was something lacking tonight. The setting came first, Gus and Shawn's class reunion, then the case. It was like Murder She Wrote, where Jessica Fletcher just happens to stumble onto a murder wherever she is.

It seemed an awkward arrangement. The show is better when Shawn and Gus horn in on a Santa Barbara PD case.
