Sweetness. Very cool skill and expertly executed.

Looking though the comments on the page there is a link (http://rudy.ca/doomsday.html) that explains how day of the week thing works.

Still, very nicely done and wonderfully entertaining.

He was my thesis adviser.
I'd hope that was interesting, but I suspect that it was a lot more mundane academia than his stage show?

Good video, fun stuff.

Cookie-fission. Nice... Haha.

Crazy. He has a very fast brain for mulitplication. This is more my speed- Ma and Pa Kettle explain math.
