I see your "any two objects are Steely Dan" and raise you "the two vertex sets of a bipartite graph are Steely Dan"

The objects don't have to be discrete. The "dartboard" counterexample to Reichenbach's Common Cause Principle is Steely Dan

Z2 X Z2 is Steely Dan. Z4 is also Steely Dan. Any finitely generated Abelian group that has only one nontrivial proper subgroup is Steely Dan

The measurement problem in physics is also Steely Dan so that one's hard to explain so Im gonna just move on to the next one

Steely Danship is recursive. two instantiations of Steely Dan themselves constitute a Steely Dan.

This process iterates.

The words "steely" and "dan" are Steely Dan

Never fear! If you accidentally mislabel a single object as Steely Dan, that's okay. The object itself plus the "Steely Dan" label constitute two objects.
