[PHINEAS]
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

[ISABELLA AND (PHINEAS)]
You take the first letter of every word, (Whenever someone sneezes)
You move it to the end and then say ‘-erb' (You no longer say "bless you")
It's like we're adding a phonetic caboose to it (Instead you play a flugelhorn)
Don't get confused, just get used to it (And give him your left shoe)

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…
