Here's what we know about Mr. Black, from Dr Seuss's Hop on Pop:
- He has a frock, black hat, and beard. (image)
- He comes back from "out of town" with Mr. Brown; implying Mr. Black lives outside of New York. (image)
- He eats a "snack" with Mr. Brown and Pup that includes a sandwich, which means he must hold of "mezonos bread". (image)
He seems pretty frum, but how many frum Jews live "out of town" anyways? And the consensus of poskim is against mezonos bread . What subgroup could he possibly belong to?
