 For what it's worth, although he hasn't (to my knowledge) actually
submitted any sequences himself, Randall Munroe has a few sequences he
could reasonably claim in the OEIS:

A129336, Digital clock semiprimes, submitted by Jonathan Vos Post and
inspired by https://xkcd.com/247/

A166079, submitted by yours truly and inspired by
