I agree with you on the great parody songs of Homer and Jethro. I also perform many of their songs and the older people just love the stuff. I have been doing Heartbreak Motel for years, but not sure I have the words just right. I will post them here and let me know if there are any corrections.

HART BRAKE MOTEL
Homer & Jethro

1. Down at the Hart Brake Motel, my room it was so small,
Ever' time I tried to smile, my teeth would touch the wall,
But I'm a-stayin' and a-payin'.
I ain't got room to change my mind.

2. I picked up my telephone. The manager said, "Hello."
He said, "What's eatin' you?" I said, "That's what I'd like to know,
An' I'm a-itchin', an' a-scratchin'.
I'm wearin' out my fingernails."

3. I walked up to the room clerk. He looked at me and said,
"You can have a room, but you will have to make your bed."
I said, "That's OK, buddy. I learned that from my ma."
Then he reached out and handed me a hammer and a saw.
And I'm a-nailin' and a-wailin'
Here at the Hart Brake Motel.

4. Here at the Hart Brake Motel, I got a room with bath.
Back home, I only had a room, and it just had a path.
This outside plumbin', it's unbecomin'.
It's really out of this world.

5. The waiter in the dinin' room, he filled my heart with cheer.
He said I would enjoy it 'cause I could eat dirt cheap here,
And he was so right. That was my last night,
And now I'm checkin' out of here.
