Okay.

If the Underground has  N  working phone numbers, and Sans makes  X  phone calls after you meet Papyrus, then the probability of a given phone (Frisk's) getting the call is  X/N . I thought there were factorials involved, but apparently not. Ambassador has previously established a lower bound on population at 666 monsters, but in all likelihood it's significantly more than that. So, best-case scenario, there are no unencountered monsters, only half of the population has cell phones, and Sans prank-calls 18 people.

But that's the best-case. And you can argue for ages on how it's not the case.

So, let me ask you a question.

How does Alphys have our number, and why does she think our number is a pizza place?

It might make sense for her to have the number in some old phone directory, but she specifically tries to order a pizza. She randomly and accidentally calls our number... on 5% of all runs.

Explain that, and I'll consider your Sans-phone argument.
