I found this:
They are saying she is too tall and too skinny, but one says she's still pretty good looking. She sarcastically says "Thanks a lot," or something to that effect. One of the guys says "Oh, she understands Russian." And Harriet replies, "Yes, I do. You fellas have a nice evening."
the 'she's still pretty good looking' part seems like it might be something a little dirtier, but whatev.
