Graduations Galore!
Unbeknownst to all the students, the Doctor showed up to save the student population from a flaming comet that was headed to the main football field. He utilized sonic technology to push it out of the way, thereby saving us all. Of course, all but a few know and appreciate.
(As an aside, I wonder if the Doctor has ever showed up at any college graduations?)
