what odd songs get stuck in your head?

right now i have pink's new song perfect (? i don't know the real title) in my head. it's not odd b/c i heard it in the car on the way home today. i have a habit of getting commercial jingles stuck in my head. in the morning there's always this one commercial for OJ and it just repeats "good morning" over and over again in a catchy tune. it's on during the news every morning. sometimes i sing it to the dogs. and don't even get me started on the luna commercials!
