Let's Spend the Night Together - S1.E3

Penny and Vince meet in the park and he invites her to dinner at his flat - purely as a friend. The food is awful but the pair get on, Penny describing how her marriage broke down, but she resists Vince's attempts to get her to stay the night. She does start to soften when he whispers sweet nothings but leaves when she realizes he has stolen them from song lyrics - though she does give him her work number.
