Lyrics:

When you left me all alone at the record hop,
told me you were goin' out for a soda pop.
You were gone for quite a while, half an hour or more.
You came back and man, oh man, this is what I saw.

Chorus
Lipstick on your collar
told a tale on you.
Lipstick on your collar
said you were untrue.
Bet your bottom dollar
you and I are through.
'cause lipstick on your collar
told a tale on you.

Verse
You said it belonged to me, made me stop and think.
And then I noticed yours was red; mine was baby pink.
Who walked in but Mary Jane, lipstick all a mess?
Were you smoochin' my best friend? Guess, the answer's 'yes'.
