You take the first letter of every word
You move it to the end and then say ?-erb'
It's like we're adding a phonetic caboose to it
Don't get confused, just get used to it

Isabella: Whenever someone sneezes
You no longer say "bless you"
Instead you play a flugelhorn
And give him your left shoe

Phineas and Isabella:
Whenever you meet someone on the street
Don't shake their hand, just stomp your feet
And your conversation won't be complete
Until you give him a big slab of meat

Phineas, Ferb, Isabella, Baljeet and Buford
So those are the rules and we hope you enjoy them
We're sure to be adding a few
As new customs evolve, well, we hope you employ them
But for right now here's what you should do?
