Apparently, this is a parody/homage to Laurel & Hardy. I'm not very familiar with Laurel & Hardy; for whatever reason, it just wasn't something my family was into. However, I think the claymation works really well for that slapsticky type comedy. Although it does have its limits; there's a part where Bert is struggling to keep the piano from falling down the stairs, and I know it's supposed to be beads of sweat appearing on his face, but it looks to me like he was suddenly attacked by leeches.
