Imagine if 'Jackass' Had an Educational Bent.

To promote a marathon of The Discovery Channel's top shows, CA Square put together "Best of Discovery," a montage of clips where men get slapped, crocs are wraastled bare-handed, bugs get eaten live, and things are inevitably blown up.

Also, I'm pretty sure somebody got struck by lightning.

In his sauciest, most vigorous key, the narrator promises "more thrills, more explosions, more dirt ... more INSANITY." Curious? The marathon kicked off this week. No worries if you missed anything; it lasts for 13 days.
