Honestly though -- how good is Karl Pilkington, and how good is An Idiot Abroad -- head like an orange, etc. This cool Skyrim mod takes advantage of this fact, by placing Karl Pilkington himself in the Skyrim universe. This is actually pretty cool.
The mod actually allows you to ask Karl Pilkington questions like a normal NPC, and has him answer using actually quote from his show and (I'm assuming) the Rick Gervais podcast.
Apparently it's still a work in progress -- for the most up-to-date info on the project head here.
