As I learned it, it went:

There was a man who had a goat
He loved that goat just like a kid
One day that goat was feeling fine
He ate red shirts right off the line
The farmer grabbed him by the back
And tied him to the railroad track
Just then the train came into sight
And that poor goat near died of fright
He heaved a sign as if in vain
Coughed up the shirts and flagged the train.

We learned many silly songs in grade school, such as:

There was, there was a crooked man
He walked, he walked a crooked mile
He found a crooked stick bent against a crooked stile
Against a crooked stile.

He bought, he bought a crooked cat
Which caught, which caught a crooked mouse
And they all lived together in a little crooked house.
