The sketch was absolutely hilarious, I found that many of the things shown I would do, like the mail sorter, or not following everyone else. Some of the examples given I already do, like "The Scrooge" as well as "Don't follow the star". I found myself laughing almost uncontrollably at the "The Sam Raimi" example.
There would be a few examples I would add,such as "Home Wrecker", setting up christmas lights in a pattern that is highly offensive to the masses. "Trimming the tree" cutting down the tree after it has been decorated.
