I wrote the original back in high school and it's been floating around my head for a long time; here's the format as I'm introducing it to the internet.
A-Poping We Will Go
A-Poping we will go,
A-Poping we will go!
We are the Cardinals!
A-Poping we will go!
A Pontiff we will find,
Who's holy, wise, and kind!
We are the Cardinals!
A Pontiff we will find!
