When I woke up that night
I couldn't make me stop
From breaking through the dark
To peek you from the door

Absorbed by the way you close your eyes
I bet you look good under your pj's

You should have knocked, she said
From time to time you learn
To learn a little something
About those times when timing is everything

I love the way your eyes
Look graceful when they're tight
And how the silence sounds
When love gets me so loud

Sing, a-a-a
Sing, a-a-a
Sing, a-a-a
Sing, a-a-a

You should have knocked, yeah
From time to time you learn
To learn a little something
About those times when timing is everything

I bet you look good under your pj's
I bet you look good under your pj's
I bet you look good under your pj's
I bet you look good under your pj's

You should have knocked, yeah
From time to time you learn
To learn a little something
About those times when timing is
You should have knocked
From time to time you learn
To learn a little something
About those times when timing is everything
