there's the rub

There’s the drawback; that’s the impediment. This term may come from the ancient game of bowls, in which rub meant some uneveness in the ground that hindered or diverted the free movement of the bowl. It was transferred to other kinds of hindrance by the late sixteenth century, but the term really gained widespread currency through Shakespeare’s use of it in Hamlet’s soliloquy: “To sleep; perchance to dream: ay there’s the rub: for in that sleep of death what dreams may come” (Hamlet, 3.1).
