english: So this was an xkcd cartoon  from a couple of years ago, and the cartoonist suggests that we should all use pass phrases, and if you look at the second row of this cartoon, you can see the cartoonist is suggesting that the pass phrase "correct horse battery staple" would be a very strong pass phrase and something really easy to remember.
non_english: Tu vidíte internetový komiks xkcd, v ktorom pred niekoľkými rokmi  autor navrhol používanie fráz. V druhom riadku navrhuje frázu  „spravne kon spinka na baterke“, ktorá by bola nielen silná,  ale aj ľahko zapamätateľná.
