The kid says,
“You said to wait ten years, so I did.”

Did you practice on the tree-like I told you?”

“Yes ma’am, I did!”

The Madam is so impressed that she walks him upstairs to the best lady in the house.
As the lady undresses, the kid walks over to the closet, grabs a broom, and starts whacking the prostitute.

The lady screams, “What are you doing kid?”

“Checking for squirrels.”
