Lyrics
Penn (singing): Today's the day, Today's the day. My fiftieth zapping, A hero my way.

The sky is blue! My MUHU too! Saving the world Is what I'm gonna do!

''Oh! When I started this,'' I was but a boy, But I'm still a boy, So I don't know what my point was!

And on my fiftieth zap, I won't switch genders, So I'll still be a boy. A boy they'll throw a surprise party for!

''Oh! Today's the day,'' Today's the day, My fiftieth zap That I will make.

And they will throw me A surprise party, And I will eat some-

Phyllis (speaking): Surprise!
