We've seen the Birthdays for Skips, Maellard, and Pops, so it cant be any of them. The most likely one is Eileen, though it could also be Benson, HFG, Muscle Man, Margaret, or even Mordecai or Rigby (it'd be interesting to see an episode from the perspective of the other park employees for a change).
