Its true that there is nothing cuter out there than a laughing baby and this baby has a laugh that could make even the grumpiest person smile. 

But it is not only the laugh that makes this baby so adorable but what he is laughing at. At a recent trip to Toy's R Us, this baby encountered a new object that had him laughing and that object was a simple water fountain. Every time mom had the fountain go off, this baby just could not resist and burst out laughing. 

I hope he never loses that kind of innocence and happiness!
