The horse ate it :)

This whole section is kind of wacko.

Ok I'll bite, what is this about? Is it some sort of expression, or idiom?

There are waaay too many hits on Google on this topic :-) Whoever wrote this sentence may have heard the story posted by the Nürnberger Zeitung in 2010 called "Oh You Holy Potato" referring to two seperate families who both cut into a potato to find the sign of the cross. What?!
