Law & Order, Season 19

[Bernard and Lupo examine a teenage murder victim]

Bernard:
Fresh haircut, his nails are clean... he's too well-groomed to be living out on the street. He even tucked his shirt in.

Lupo:
He buttoned his top button.

Bernard:
Did you walk around like that when you were his age?

Lupo:
Not unless my mother made me.
