Hey, without kanji you get にわのにわにはにわとりはにわかにわにをたべた (or worse, "niwa no niwa niwa niwatori wa niwaka ni wani wo tabeta").

With kanji, it makes perfect sense: にわの庭には鶏は俄に鰐を食べた。You can easily look up each of those characters to determine that I am saying "Two chickens in Niwa's garden suddenly ate an alligator." (It happens all the time.)
