This is a follow-up on Debbie from Utah's post above.
Here are all the words to the hen and the rooster from my dad's version, but if anyone knows more verses, I'd be happy to have them:

The hen and the rooster lived away out west,
said the hen to the rooster, "hun, I love you best"
said the rooster to the hen, "hun, I know you lie,
since I saw you in the alley with a big Shanghai".

Ain't it so
now listen honey, I don't know.
Now sweetie don't you lie to me,
cuz' I'm not as dumb as I used to be.

I once knew a doctor by the name of Peck.
He fell into the well and broke his gosh-darned neck.
It served him right that he broke his bones,
he should have tended to the sick and left the well alone.

Ain't it so.....etc

We put some Easter eggs under our old hen,
for the kids to find on Easter morning,...then
the rooster came in and saw the green and red
Hopped the fence and killed the neighbor's peacock dead.

Ain't it so....etc

I bought a pair of combination underwear,
to keep out the cold and the wintery air.
I wore 'em six months, and without exaggeration,
when I went to take them off I had forgot the combination.

Ain't it so....etc

I went to a dance last Saturday night,
when all at once, I had a terrible fright.
I heard a loud rip, and I knew at a glance,
that I was quickly losin' my desire to dance.

Ain't it so.....etc
