Lennon-McCartney I got something to say that might cause you pain If I catch you talking to that boy again I'm gonna let you down and leave you flat Because I told you before, oh you can't do that. Well it's the second time I've caught you talking to him Do I have to tell you one more time I think it's a sin ? I think I'll let you down and leave you flat Because I've told you before, oh you can't do that. Everybody's green 'Cause I'm the one who won your love But if it's seen You're talking that way, they'd laugh in my face. So please listen to me if you wanna stay mine I can't help my feelings, I'll go out of my mind I know I'll let you down and leave you flat Because I've told you before, oh you can't do that. You can't do that, you can't do that You can't do that, you can't do that You can't do that. Everybody's green 'Cause I'm the one who won your love But if it's seen You're talking that way, they'd laugh in my face. So please listen to me if you wanna stay mine I can't help my feelings, I'll go out of my mind I know I'll let you down and leave you flat Because I've told you before, oh you can't do that.
