The little guy in many of the scenes was Charley Hall. I think he was as funny as L&H. I've seen some clips a hundred times and I, still, laugh out loud.
@0:56 - Woah, was Hardy about to double break the 4th wall, both figuratively and literally....by throwing a brick at us? O_o lol XD It's amazing how much Laurel & Hardy's work stands the test of time :)
