Lyrics:

Be sure it's true when you say, 'I love you'
It's a sin to tell a lie
Millions of hearts have been broken, yes, yes
Just because these words were spoken
You know the words that were spoken? Here it is
'I love you, I love you, I love you, I love you,' ha-ha-ha
Yes, but if you break my heart, I'll break your jaw and then I'll die
So be sure it's true, when you say, 'I love you,' ha-ha
It's a sin to tell a lie
Now get on out there and tell your lie, what is it?

Be sure it's true
When you say, 'I love you'
It's a sin, a double sin, to tell a lie
What I said
