While we're on the subject of pareidolia, it turns out that Mitchell and Webb have taken this topic on as well...
They go after all sorts of religious and new age nonsense on their show. I spent wasted a good part of yesterday watching the first two seasons of the show in their entirety.
They had one skit of a couple looking to buy a used wardrode at a yard sale. When the proprietor informs them that the wardrobe has a portal to Narnia, they ask if they can take a "test ride".
SPOILER ALERT: (I couldn't figure out how white out the text; the "font" tag doesn't seem to work here in the comments.)
Moments later, they emerge from the wardrobe in full medieval/fantasy attire announcing how they'd just spent years in Narnia. But then they decline to buy the wardrobe because "it was a bit too Christian for their tastes."
I think my favourite so far is the Nazi uniform one: http://www.youtube.com/watch?v=JEle_DLDg9Y
In the tradition of "Dave Allen At Large" (remember that one?).
My favorite one is "History Of Numberwang", namely Colosson's rampage.
"I AM COLLOSON! I AM NUMBERWANG! THE WORLD IS NUMBERWANG, THEREFORE I AM THE WORLD! YOU MUST ALL DIE!!!"
Try Dara o'Briain for some more chuckles- I love his comparison of dieticians and nutritionists to dentists and toothyologists
