From Growing up in Public (1980) by Lou Reed

Smiles (Fonfara, Reed) - 2:44

Smiles, I was taught never to smile
I was told the stylish smiles of buffoonery
Chicanery and larceny abound

My mom said unless someone sticks you right in front of a camera
A smile is the last thing that you wanna do
Those smiles, those mirthless toothy smiles

Smiles, they all smile on TV
The quizmaster with his withered crones
The talkshow hosting movie stars
The politician licking feet

The mugger, the rapist, the arsonic lover
All smile out from the news, at one time or another
Those smiles, those garish sickly smiles

When I was young my mother said to me:
"Never, ever, let anyone see that you're happy"

Smiles, never, ever let them see you smile
They'll always put you down
With those smiles, never, ever let them see you smile
They'll always put you down
With your smiles, never, ever let them see you smile
Don't you know they'll make you go

Doo, doo, doo, doo, doo, doo, doo, doo ...
