3. The Slumber Caper

Complete story — includes the ending

Marcia is accused by school principal J. P. Randolph ( E.G. Marshall ) of drawing an unflattering picture of her English teacher Mrs. Denton, who was named in an insulting remark written beneath it. Mike and Carol believe Marcia's claim that she merely copied a portrait of George Washington and never wrote Mrs. Denton's name on the drawing. They allow Marcia to have her planned slumber party but she still has to serve a week's detention at school. Marcia becomes convinced her best friend Jenny was the guilty party and "uninvites" her. The Brady boys conspire to disrupt the party and place itching powder in the girls' sleeping bags. While the girls clean up, Marcia's friend Paula (Chris Charney) admits that she found the drawing, which Marcia had left behind in her desk, and wrote the remark with the intention of no one except Marcia seeing it. Marcia realizes that in accusing Jenny she did the same thing her principal did in accusing her, and reinvites Jenny to the party. Guest stars: Hope Sherwood (daughter of Sherwood Schwartz) as Jenny Wilton, Barbara Bernstein (daughter of Florence Henderson) as Ruthie, and Carolyn Reed (daughter of Robert Reed) as Karen.
