S6E13 · Secret Santa

Complete story — includes the ending

Michael is outraged when Jim allows Phyllis to be Santa at the office Christmas party, and retaliates by dressing first as Santa, then Jesus. David reveals to Michael that there is a buyer for Dunder Mifflin. He will most likely be fired; the Scranton staff will stay on, much to their relief. Meanwhile, Oscar has a crush on Matt, the new gay warehouse worker, and Andy and Erin continue to flirt, which starts out badly when Andy gives her "the Twelve Days of Christmas" and the birds from the first few attack her, but picks back up with the twelve drummers drumming.
