The Birthday Song
What day is today?
It's _____'s birthday,
What a day for a birthday,
Let's all have some cake
The cast sings a different birthday song than the one used in our time (different lyrics and melody). Either because in the future this new song is the norm, or because Warner Music Group still makes copyright claims against our currently used song.
