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.
