While Punky dressed in all orange because it was Kevin's favorite color, no reason was mentioned for her plucking her eyebrows.
Kevin: I had no idea you liked me.
Punky: How could you not know? I dressed in all orange. I plucked my eyebrows!
Kevin: You did? Oh man, doesn't that hurt?
Punky: It's like pricking yourself in the face with a porcupine.
Margaux: (to Punky) You finally learned to coordinate colors. Unfortunately, you chose orange...
Kevin: The red wire goes to the red wire, and the black wire goes to the black wire.
Punky: You're a god.
Cherie: Punky's trying to install a new stereo.
Kevin: Yeah? What kind did ya get?
Punky: (lovestruck) You're a god!
Punky: (briefly snapping out of it) I said God, you must know everything about stereos.
Punky: I was crazy to think you liked me.
Kevin: Oh, I do like you! But I like you as a friend.
Punky: That hurts worse than eyebrow plucking.
