Mad Men: Season 6, Episode 08 [The Crash]

Words of love, so soft and tender
Won't win a girls heart anymore
If you love her then you must send her
Somewhere where she's never been before
Worn out phrases and longing gazes
Won't get you where you want to go, no!
Words of love, soft and tender
Won't win her

You oughta know by now
You oughta know, you oughta know by now
Words of love, soft and tender
Won't win her anymore
 [bad word] 
You oughta know by now
You oughta know, you oughta know by now
Words of love, soft and tender
