Mr Potatohead and Markan Priority

I've not yet had a chance to see Toy Story 3 - I'm hoping to take Nina shortly, but it appears that Mr Potatohead has been branching out into biblical studies. Mark Goodacre links to a YouTube video explaining Markan priority in the Synoptic Gospels. It can only be a matter of time before he coerces Buzz, Woodie and the slinky dog into explaining the documentary hypothesis.
