This video was actually on America's Funniest Home Video many years ago but it always seems to resurface and it also never gets old. 

One baby is adorable, so imagine two! Now double that and make it quadruplets and all laughing at the same time... It becomes the cure to all bad days everywhere. These quadruplets are so hilarious and adorable, you will want to watch it over and over. 

So if you are having a bad day, watch this video and give yourself a much needed break and if you know someone whose day might be a little off, send it to them and turn that frown upside down!
