The 2009 Jonathan Creek special had a hilarious segment with people watching 3D porn. Just their expressions, and the way they dodged at the end, conveyed everything the viewer needed to know.
Actually, the prequel re-release will end up being like 3D porn anyway, because so much of them could be replaced with Lucas yankin' it in front of a green screen (shouting 'meesa!' at the end) and they would pretty much be the same movies.
