Retroactive crossovers part 2!

Yeah, one more MTV crossover.
Should've done it last time.

From the link...

Now...if only there were a way to work Aeon Flux in there....it'll come to me someday...

This is as close as I can get...

Beavis & Butt-Head were on Letterman.

Charlize Theron was on Letterman.

Charlize Theron played Aeon Flux in the movie.

Theron also voiced Aeon in the video game prequel to the film, which was meant to bridge the film, and....

....the animated series.

Best I can do.
