The director of the event asked if I wouldn't mind filling some time by fielding questions from the old folks, which I gladly did. Some of the questions they asked were:
"Do you have any children?" Yes - a daughter, Ninnette, an elf like me. She currently works in the christmas magic department, but spends most of her time backpacking around Europe and hanging out with undesireables. Of course, what daughter listens to her parents? i'd like it if she calls once in a while. (Sympathetic nods from old ladies)
"What do the reindeer eat?" Unlike regular reindeer, magical talking reindeer (I go for the rankin-bass style reindeer) can tell you food preferences, so while they mostly eat oats, some of them like other things. Donner likes flowers and Blitzen has a penchant for bacon.
Other good ones - "Does wanting something naughty like lingere put you on the naughty list?", "what do you do the rest of the year", "what is Santa's favorite food" (I said polar bear, or french fried walrus, both of which got gasps of outrage), "does Santa have sex" (these old folks are dirrr-ty), "does Santa have any health problems".
oh - "what did you get Mrs. Claus?" - I said that since I can have the elves make anything, that gift-giving in the Claus household is more about finding rare things or making things - Mrs. Claus knit me a new afghan and I found her a 1950's-era sovet cold war robot.
