If you spend your life dealing with calls from the public you eventually become utterly unshockable.
I used to work as a medical information officer. Most of the calls we did were quite sensible, but some of them!
I once had a man phone us to ask if he could use spermicidal jelly to keep aphids off his organic hop plants. That was a good one.
And we had a regular caller, who used to ring us on thursday with full lurid details of what she was going to get upto on a 'Dirty weekend' (her words) and ask for contraceptive advice (we made contraceptives).
