Mythbusters' scientific jesters Adam Savage and Jamie Hyneman are freaking hillarious. If you are a fan of Alton Brown and you haven't watched Mythbusters on the Discovery Channel (USA and Canada), go set your Tivo now! I love Alton Brown's Good Eats because he weaves food science, pop culture and common sense into recipes on a theme. Adam and Jamie have a similar take on urban myths -- like the one about how a Bible can stop a bullet, or how you can test positive for opium if you eat a poppy-seed bagel -- and they not only go through the theory, but they show, through trial and error, how something may or may not be possible or even plausible.
The bonus is that Discovery Channel Canada has been running Mythbusters at midnight, which is great when The Daily Show is in reruns.
