I remember when XKCD was 3 digits. I don't think I knew about it when it was 2 digits.And I recall how I was at the edge of my seat when he got to comic 401, 402, 403.When you click "next" from 403, note it goes to comic #405. Same thing if you go to #405 and then select "previous", it jumps to comic #403.https://xkcd.com/403/#xkcd
