Punky Brewster - S04E19 - One Plus Tutor Is Three.

Punky has a D in math, a subject that she hasn’t been doing very well at. As a result, Henry and Punky’s teacher have agreed that she needs a math tutor. With a name like Walker Wimbley (Mark-Paul Gosselaar), Punky thinks her tutor will be a nerd. But Walker turns out to be a Casanova who tests the friendship between Punky and Margaux by falling head over heels for Margaux—crushing a love-struck Punky. When Walker becomes bored with Margaux, he decides that he likes Punky. Explaining his behavior to Punky, Walker says “All that blonde hair blinded me.“ Realizing what a jerk Walker is, Punky stands up for Margaux. Cherie and a shocked Margaux overhear it. With Margaux and Cherie’s help, Punky gets even with Walker, and they make him leave the apartment.
