Lyrics: Madness. The Madness. Be Good Boy.

Sitting by the fire
It seems only yesterday
Look how you've grown
Now the time has come
For me to say:

You can do whatever you feel
I guess I'm right whenever you feel

Don't forget to brush your teeth
Or comb your hair
There's people out there to meet
Careful when you smile
When you walk into the room
A smile worthless unless you mean it to

You can take whatever you need
You can leave whenever need be

Be good boy don't fall mother knows best
Be good bot and choose mother knows best

Take a look at what you're going to do
Ooh think boy don't be led take the lead boy
I don't want to have to tell you again
Don't let me down my good humoured man

You can have whatever you want
Maybe I'm wrong whenever you want

Be good boy don't fret mother knows best
Be good bot don't cry mother knows best
Beholder of disguise so choose mother knows best
You better be on your best behaviour
Come visiting day
