Am I the only one?

For days once, not all that long ago, I have the theme song from the Muppets running through my head, then suddenly one day it all changed to the theme song to the 4400.
Another time I got stuck on the thought, "Why are is it that hoot owl and moo cow are the only animals that are referred to, by small children, including the sound the animal makes and the name of the animal?" One never hears of a meow cat, or a bark dog. There is no cluck chicken or oink pig.
Have you ever had the lyrics and tune of a song you know that you've never heard before running through your head, yet like most other songs, it's only the one line and it eventually drives you insane? Please note that I am not a song writer and music it not a strong point of mine either.
My husband and I argue with our cats, and tease them, in their own language. We also have conversations between us that is all meowing. Not just at home, but in the grocery store also.
