My Erdős number is 2:
Juggling Drops and Descents
Joe Buhler, David Eisenbud, Ron Graham, Colin Wright
American Mathematical Monthly, Vol. 101, 1994, pp. 507–519
Minimal Decompositions of Graphs into Mutually Isomorphic Subgraphs
F.R.K. Chung, P. Erdos, Ron Graham
Combinatorica 11 (1981), 13-24.
My Bacon number is 3 if you count television appearances: I was on Child Genius, S3.E2 (2015), narrated by Celia Imrie
Celia Imrie was in Frankenstein (1994) with John Cleese
John Cleese was in The Big Picture (1989) with Kevin Bacon
So my Erdős–Bacon number is 5.========
As an addendum, I also have an Erdős number of the second kind:
Cliques in random graphs.

So it's 3.
