A quote from ‘A Connecticut Yankee in King Arthur’s Court’ by Mark Twain.
" But don’t you know, there are some things that can beat smartness and foresight? Awkwardness and stupidity can. The best swordsman in the world doesn’t need to fear the second best swordsman in the world; no, the person for him to be afraid of is some ignorant antagonist who has never had a sword in his hand before; he doesn’t do the thing he ought to do, and so the expert isn’t prepared for him; he does the thing he ought not to do; and often it catches the expert out and ends him on the spot. Well, how could I, with all my gifts, make any valuable preparation against a near sighted, cross eyed, pudding-headed clown who would aim himself at the wrong tree and hit the right one? And that is what he did. He went for the wrong tree, which was of course the right one by mistake, and up he started. "
