There is a Mr. Plow! It's under "Southwest Region". Many others could be considered Mr. Plow as well, Gordie Plow, Herbert H. Plow, Marco Plowo and more.
Yes! Thank you for finding that! (How did I miss that?)
There's a Mr Plow because that's his name, Mr Plow.
Mr plow is a loser (and I think he is a boozer) so you'd better make that call to the Plow King
