I didn't do my research. Had I come to IMDb before seeing Wall-E, I would have known that we would be seeing Presto. It's a great Looney Tunes style short that pits a rabbit against his magician, all for a carrot. It actually had me laughing. Not just chuckling, but laughing and since you can't see the original Looney Tunes I used to love, it was a refreshing change to have a short cartoon do that for me. I'd almost forgotten what it was like. The animation is much better than the old favourites, but not quite as detailed as something like Shrek or even Wall-E itself. They keep it simple and light on its feet. Works perfectly in my opinion. I would gladly sit through Presto again if I went to see Wall-E a second time.
