Nancy and Johnny / The Knife in the Window

Last Saturday night young Nancy laid sleeping, and into her bedroom young Johnny went a-creeping,
With his long fol-the-riddle-i-do right down to his knee. 
He said, “Lovely Nancy, may I come to bed to you?” 
She smiled and replied, “John, I'm afraid you'll undo me with your long fol-the-riddle-i-do right down to your knee.” 

His small clothes fell from him and into bed tumbled, 
She laughed in his face when his breeches he fumbled 
With his long fol-the-riddle-i-do right down to his knee. 
 “My breeches fit tight, love, I cannot undo them.” 
She smiled and replied, “John, you must take a knife to them with your long fol-the-riddle-i-do right down to your knee.” “
My knife will not cut, love, it ain't worth a cinder.”
She smiled and replied, “John, there's two on the window with your long fol-the-riddle-i-do right down to your knee.” 

He picked up the knife, and he unlaced his breeches. 
He undressed his breeches, and into bed he tumbled 
With his long fol-the-riddle-i-do right down to his knee. 
All the long night how they rolled and they tumbled. 
Before daylight i' the morning Nancy's nightgown he crumbled 
With his long fol-the-riddle-i-do right down to his knee. 
 Now nine months being past, it fell on a Sunday, 
A child it was born with a knife-mark in the window with a long fol-the-riddle-i-do right down to his knee.
