Last night, I was the victim of an unprovoked assault on my senses. Mainly my eyes and ears suffered, but after the attack, I found that I’d lost my appetite, too. The perp in this case was Bear Grylls, and the weapon was a commercial for his extreme wilderness reality series, Man Vs. Wild.

I’ve seen some nasty things in horror movies over the years, but I kid you not, the Wes Cravens of the world have nothing on Discovery Channel’s ad department. The most horrific moment arrives at the 17-second marker, when Grylls bites the head off the nice little froggie (pictured just before his demise, at left). Of course, my morbid sense of duty forces me to share the experience with all of you. Watch the video by clicking here — that is, if you don’t mind fasting for the next 24 hours.
