Lyrics:

I've been his friend since we were little babies
I was a comfort to his mother and a pal to his dad
Before they passed away they said,
'Please take care of our Davy
You may be the only friend he ever will have'
Davy the fat boy, Davy the fat boy
Isn't he round? Isn't he round?
What do he weigh folks?
Can you guess what he weigh?
It's only a quarter
Win a teddy bear for the girlfriend
Or something for the wife
You got to let this fat boy in your life

I think we can persuade him to do
The famous fat boy dance for you
Give me half a chance
I just know you'll like my fat boy's dance

Davy the fat boy, Davy the fat boy
Isn't he
Isn't he round?
