There were others in the series, too. I can't find a video of it right now, but if you are like me, this song has been running endlessly in the back of your mind for most of your life:
When you tell one lie, it leads to another
So you tell two lies to cover each other
Then you tell three lies and, Oh Brother,
You're in trouble up to your ears!
So you tell four lies to try to protect you
Then you tell five lies so folks won't suspect you
Then you tell six lies and you'll collect
A life filled with worries and fears
'Cause you can't remember how many lies you've told
And half the things you say aren't true
And sometime you'll slip up, you'll trip up and then
Whatever will become of you?
So you lie and lie without even trying
And each lie you tell will keep multiplying
'Till the whole wide world will know you're lying
Then you'll be
And you should!
When you lie, you're closing the door
On everything good
I never actually listened to or understood what the lyrics of these ads were getting at until I heard myself singing them when I was much older. And of course this realization came far too late for the ads to have their intended effect of guilting me into mormonism.
