Ada sings and speaks complete nonsense

I have no concrete explanation for whatever it is that Ada is singing about or talking about in this video. The nonsense started with Kevin asking her what her theme song to "Worm Day" would be (so I guess we could blame a large chunk of the wierdness on him). 

Enjoy Ada singing "Han (or is it Hon?) I love you I don't care" and discussing the fate of polite children and what we will eat for dinner.
