We're in for a very special treat this Thursday when The Office celebrates the holidays with an hour-long episode. That means even more of Michael's awkward Santa impersonations, but a very special guest will be stopping in for the festivities, too: Holly! As previously reported, Michael's ex is coming back — perhaps for good? She's absent from these sneak peek photos, so we'll have to tune in on Thursday to see Michael's reaction to her return. Until then, check out the rest of the pics as the employees celebrate the season!
