If you've been to a handful of children's birthday parties in the last ten years, you are probably aware of this odd trend of adding the words "Cha cha cha" after every line of the Birthday Song. This seems to happen at places where cheap, teenage labor is doing the entertainment. It does add some fun spice to the song and I like it because it diverts attention from any out-of-tune singing I might be doing. In fact, I think we ought to add "Cha cha cha" to a lot more songs, namely Amazing Grace and the Star Spangled Banner.
