Neil Patrick Harris' adorable twins sing good morning

Like many people, (we assume) we sometimes sing to ourselves when we're chilling at home. But unlike say, Neil Patrick Harris' incredibly adorable twins Harper and Gideon, we are neither super adorable, the children of famous actors or this creative.

So please, please enjoy the following video, in which Harper and Gideon treat the world of NPH's Facebook (or Bookface, as Gideon calls it) to renditions of the Star Wars theme, Good Morning from Singing in the Rain, a made-up song about My Little Pony and lots of general cuteness. Oh and stay all the way till the end for an excellent David Burtka cameo.
