Who met a young lady, was drawn,
His hormones a-swell,
To ring her door bell,
She answered, he let out a yawn.
"You poor little darling", she said,
Then took his hand and gently led
The chap down the hall;
With no qualms at all,
She undressed and put him to bed.
She turned off the lights, "I'll be scoring".
He told himself, his heart a-soaring .
Then she turned around
And guess what she found?
Him fast asleep, happily snoring!
