"Saturn, on the other hand, perfected a more gentle method of adding to its atmosphere. Instead of taking on its heavy elements in one massive collision, it instead gobbled up a bunch of smaller objects that were less massive than Earth. (For mythology buffs, it should be pointed out that there is currently no evidence that Saturn ate five such objects, then tried and failed to eat Jupiter, which it then vomited up. But I'm not seeing any evidence against it, either.)" - Brian Chang
