All Hat No Shekel

(Also, "Small Hat No Shekel")

Said of or in reference to an outspoken Jew who has neither the influence nor resources to back up his preposterous claims or threats. (Cf. "All Hat No Saddle")

Saul at the corner deli is just "small hat no shekel" -- for all his talk of "friends in high places," why is it he's still slinging corn beef hash?
