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
