Okay, so my last night's masterpiece:

I was a non-involved observer as an elderly, but apparently able-bodied, woman went up a shipboard stairway to meet the pope. She met the pope at about the top of the stairs, but didn't recognize her, probably because she was wearing ordinary, if slightly flamboyant, street clothes and a prominent blond hairdo. Her (the pope's) identity was promptly established (not quite sure how) and, as the two women walked out of sight, the pope mentioned that the blond hair was actually a wig, as she keeps her head shaved. The apparent duration of the whole thing wasn't much more than a couple of minutes, but it was...interesting....
