Sex and the City Season 3 Episode 7

Dennis: I think I'm in love with you, Charlotte.
Charlotte: Well you can't be in love with me, you're married to my friend.
Dennis: Yeah, things haven't been going so great with us lately, and ever since I saw you that night at dinner, I couldn't stop thinking about you.
Charlotte: This is not...
Dennis: No, no, come on, don't leave, don't leave!
Charlotte: You kept all of your great single friends away from me just so you can cheat on your wife? (slaps Dennis) You should be ashamed of yourself!
Dennis: You're such a spark plug, I love that about you!
Charlotte: I'm not interested in starting some married man's car!
Dennis: No, don't leave! Please! Please! I love you!
