How would I format the attribution and where would it go in the book?
It depends on how you want to include it in the context. In stories I've used a number of options:
A little later he says, "You know, Shakespeare was wrong!" She gives him an odd look, so he quotes:
"As You Like It: Act 2, Scene 7
All the world's a stage,
And all the men and women merely players.
They have their exits and their entrances,
And one man in his time plays many parts,
His acts being seven ages. ..."
or
Mo walks out onto the field for the opening ceremonies of the game. When he walks out the team manager holds the rest of the team back as the announcer says, "All please stand to welcome home our own Mo Walker!" The crowd stands to cheer while the stadium speakers come alive with music and song:
"Now he couldn't move a mountain
Or pull down a big oak tree,
But my daddy became a mighty big man
With a simple philosophy ..."
The crowd joins in the singing as Mo turns around while waving his cap and the tears run down his cheeks. In the VIP box Mo's wife, father, and step-mother are also crying at his welcome home.

Do what you do do well
Do what you do do well boy
Do what you do do well
Give your love and all of your heart
And do what you do do well
Ned Miller, 1965

Kyle laughs, "I think it's the or something. Now let's get these trailers attached to our vehicles, and check to make sure we haven't forgotten anything. We've got guests meeting us here in a few minutes."
"Guests! What guests? We don't need no stinking guests."
Kyle laughs, and suddenly has an even funnier thought. "Brain, that Cheech and Chong line has become a part of our culture."
"Oh, it's more ingrained than you know. It was originally said by Humphrey Bogart in a nineteen forty-eight movie."
"Are you serious?"
A female voice behind them adds, "He's partially right, Kyle. The line does come from the movie 'The Treasure of Sierra Madre,' but it was spoken by Alfonse Bedoya, not Bogie. It was also used in other movies like 'Blazing Saddles.' Cheech and Chong may have used it in comedy routines, but it was never actually in one of their movies."
Kyle turns, and sees Dr Haywood is the source of the voice and the information. Her husband, Marc, is standing beside her. They're both dressed in desert camouflage BDUs (Battle Dress Uniforms). What really surprises Kyle is while he knows Marc is a captain, Dr Haywood is wearing the oak leaves of a major. Kyle introduces the couple to Ryan, and mentions his nickname is Brain.
