Well, I survived the first day of my return to teaching.
Conclusions:
1. I should not use the characteristic function of the rationals as an example of a weird function if not everyone in the class is familiar with the concept of rational numbers.
2. Using the photoelectric effect as an example may not have been the best idea, either.
I'm glad I at least thought of the divisor-counting function as an easy example of a function that only makes sense for integers - somehow I didn't last year... (I was almost tempted to use integer complexity, but that is obviously a terrible, terrible, idea.)
