I have had the Wonder Pets song going through my head for the past three days. We watch the Wonder Pets because it's on at 10:30 in the morning, which happens to be the time that Sadie takes her nap each morning. When she's having a hard time going to sleep we watch half an episode of the Wonder Pets and by the end of it she's usually asleep or at least calm enough to fall asleep.
A few days ago when we were in the car she started to fuss so I started to sing part of one of the songs. It was "What's gonna work? Teamwork! What's gonna work? Teamwork!" Each time I said "teamwork" she would start to giggle hysterically.
Now we've realized that any part of the Wonder Pets songs make her laugh, which is great because the song is stuck in my head, on replay, so I've been singing it a lot.
And now it looks like I've got to go sing it again because Sadie is having a fussy day and it has turned into a fussy night.
