You think you're sweet and you think you're true, But how do you know what you will do When Mr. Wrong comes along Some day? You think you're kind, you think you're fair, But you turn around and he is there, Mr. Wrong, comes along Some day. Opportunity need not knock If your door doesn't have a lock When Mr. Wrong comes along Some day. Just a word, just a smile And you find you've slipped a mile. Walk along with your air of pride Then there's a shadow by your side When Mr. Wrong comes along Some day.
