O Tannenbaum
performed by Vince Guaraldi Trio

Michael comes into the office as Santa and is outraged that Jim had already allowed Phyllis to be Santa at the office Christmas party this year. Everyone seems to enjoy having Phyllis as Santa, but Michael continues to try and steal her thunder, prompting Jim to tell him to cease and desist. Michael then rearranges his costume into a Jesus outfit and starts interrupting Phyllis while she's giving out the Secret Santa gifts. When Jim stops Michael again, Michael calls CFO David Wallace to complain. David asks not to be bothered as someone made an agreement to buy the company, and David and presumably everyone else will lose their jobs after the fact.
