1. "Reuben, Reuben, I've been thinking," said his wifey dear.
"Now that all is peaceful and calm,
The boys will soon be back to the farm."
Mister Reuben started winking and slowly rubbed his chin.
He pulled his chair up close to mother, and he asked her with a grin:

CHORUS 1: "How 'ya gonna keep 'em down on the farm after they've seen Paree?
How 'ya gonna keep 'em away from Broadway, jazzin' aroun' and paintin' the town?
How 'ya gonna keep 'em away from harm? That's a mystery.
They'll never want to see a rake or plow,
And who the deuce can parley-vous a cow?
How 'ya gonna keep 'em down on the farm after they've seen Paree?"

2. "Reuben, Reuben, you're mistaken," said his wifey dear.
"Once a farmer, always a jay,
And farmers always stick to the hay."
"Mother Reuben, I'm not fakin', though you may think it strange,
But wine and women play the mischief with a boy who's loose with change."

CHORUS 2: "How 'ya gonna keep 'em down on the farm after they've seen Paree?
How 'ya gonna keep 'em away from Broadway, jazzin' aroun' and paintin' the town?
How 'ya gonna keep 'em away from harm? That's a mystery.
Imagine, Reuben, when he meets his pa:
He'll kiss his cheek and holler, "Oo-la-la!"
How 'ya gonna keep 'em down on the farm after they've seen Paree?
