Erm..

Terrible.

Ooer.

A slideshow. But worse than that. Oh yes, much, much worse. Ugh, patriotism makes me sick.

Hrrmm...

You can draw, no doubt about that. Just take your time with the animating process itself. Although I enjoyed the imagary, it was hjust far too slow-paced. Try to avoid using motion tweening aswell.

Don't use sprites either. Ever.

Keep at it.

Five!

EROTIC! EROTIC! EROTIC!

Awesome.

"Everyone know's it's Butters!"

"Uhh, tha-thats me."

Great.

But you forgot some classic quotes;

For instance, the crying Cartman sound when Kyle beats him up (It's Christmas in Canada episode).

But I suppose at the end of the day, there are far too many Cartman phrases to pack into one Flash.

Good work.
