Wargle argle fargle dragon
Jeff Bridges appeared as a "spook" in the film Seventh Son. His performance was deemed to be pretty much incomprehensible, more so than he was in True Grit even.
At one point in the film Mr Bridges delivers a "zinger" after something happens with a large winged lizard. According to Mark the line appeared to be "Wargle argle fragle dragon".
Simon thinks that this is in fact the name of a Steeleye Span album.
