Help me find a Living Single episode?

Theres an episode of Living Single and im trying to get the name.

Its when Regine and Khadijah have a falling out and Regine plans to move out. In the end she doesnt and they make up...

but in the episode(unless im getting confused with a different episode) there's a scene where either Regine or Synclaire is playing with a barbie doll and is obsessing over it because it looks like her. She then makes a comment to Maxine saying she's jealous because the only thing that looks like her is a mop.

Please help me find one or both of these episodes thanks
