SPEAKER 1: What is something that makes you feel old?
SPEAKER 2: Oh, so a lot of pop culture things, especially
in a teaching context.
Like, for years I was in the habit of using Seinfeld references, which is
a very popular American funny TV show.
But drifting, I guess, out of date, recollection.
I have been, for the past few years, using
The Office, because The Office, especially online,
has continued to be popular among kids today.
We've recently switched to using Nintendo characters, which
have kind of been around now for decades and keep
kind of getting refreshed in some way.
So that's been helpful.
But it's whenever I make a comment like that about some show
that some students don't get, that I do feel old.
And in fact, this sort of canonical demonstration that we do in CS50
is when in a discussion of binary search, which
it means searching efficiently by dividing a problem in half
again and again.
And for this we've used, for 17 years, a phone book.
And I think we hit the point a year ago where someone online asked,
What is that he's holding?
And--
SPEAKER 1: What is a phone phone?
SPEAKER 2: --that make me feel old.
