I like the converting scene there. It is cool that it ties in with the Conan's Witness episode. I also like the emp and wonderful life one too, but I really like the converting one just because it ties in with that other episode.
I am never really one to avoid Christmas, but the fact that this video is about two months late from when stores started promoting Christmas does make a point that some places start celebrating the holidays a bit too early.
The only thing in that video I would not try is the papershreder one. Sure, it is a good way to destroy those cards, but knowing my luck one of those would have money in it and that's a quick way to lose ten or twenty dollars.
