Funniest Mario flash ever?

Even though my first (And...only...) submission to NG was a Mario movie, I totally see what you mean by how it's overdone. Also, the way you said the dialouge was just hilarious to hear.

Eh

No story or reason for them fighting, the fighting itself was uninteresting, and scenes went by too fast.

It's a decent/good quality in terms of animating, but lacks plot, and the concept of "2 sprites fight lawl" is overdone.
