I couldn't stop laughing
I know most of it is not funny but what was funny was each of the neighbors showing up at the Walker's door singing to them and dropping off decorations. That and the fact that Nick "failed" to tell Michael why he was pushing the mansion off on him and what was going to happen. He was way too eager to sell it to him cheap, even Michael's wife was skeptical.
The part where I really couldn't stop laughing is when Michael is trying to get coffee and the server kept trying to buy Christmas themed drinks and then the news came on talking about Michael being the town's Grinch. The server exclaims laughing, "hey dude, that's you!"
