This is the tale of Mister Morton
Mister Morton is who?
He is the subject of our tale
And the predicate tells what Mister Morton must do

Mister Morton walked down the street
Mister Morton walked
Mister Morton talked to his cat
Mister Morton talked
(Hello, cat. You look good.)
Mister Morton was lonely
Mister Morton was
Mister Morton is the subject of the sentence
And what the predicate says, he does

Mister Morton knew just one girl
Mister Morton knew
Mister Morton grew flowers for Perl
Mister Morton grew
Mister Morton was very shy
Mister Morton was
Mister Morton is the subject of the sentence
And what the predicate says, he does

The subject is a noun, that's person, place or thing
It's who or what the sentence is about
And the predicate is the verb, that's the action word
That gets the subject up and out
Mister Morton wrote Pearl a poem
Mister Morton wrote
Pearl replied in the afternoon
Pearl replied by a note
Mister Morton was very nervous
Mister Morton was
Mister Morton is the subject of the sentence
And what the predicate says, he does

The cat stretched, the sun beat down
A neighbor chased his kid
(Come here kid - come on!)
Each sentence is completed when
You know the subject did

Mister Morton knocked on her door
Mister Morton knocked
Mister Morton sat on her porch
Yes, he just sat there and rocked
Mister Morton was a nervous man
When she opened up the door he ran

Mister Morton climbed up his stairs
Mister Morton climbed
Mister Morton rhymed pretty words
Mister Morton rhymed
Mister Morton was lonely
Mister Morton was
Until Pearl showed up with a single rose
Who says women can't propose?
Now Mister Morton is happy
And Pearl and the cat are too
They're the subjects of the sentence
And what the predicate says, they do
