My Sister, Benedict Arnold was the fifth episode of Season 3 of the Blake Foster's Adventures of The Brady Bunch.

Synopsis

Greg and Marcia use their dates to get back at each other; the younger Brady siblings prepare for the school carnival by building a dunking tank.

Summary

Greg is furious that Marcia is dating his school rival, Warren Mulaney (Gary Rist). After a date with Warren, Marcia decides to not date him again. When Greg demands Marcia not see him again, she invites him home to spite Greg. However Greg has brought home Marcia's rival, Kathy Lawrence (Sheri Cowart). Marcia and Greg clash over this and Mike admonishes them for using Kathy and Warren to make a point. When they go to the other room to apologize they find that Warren and Kathy have befriended each other and left together. In the subplot, Alice, Peter, Cindy, Bobby, The Brady's Siblings, Ryan, Winnie the Pooh, and Kids World's Adventures Team work on the dunking machine for the school carnival.

Storyline

Marcia is excited that a high school boy has asked her out on a date. Marcia tells Greg about the date and wants his opinion about the boy. Without yet telling him who the boy is, Greg tells her that the only boy who he would object to is someone named Warren Mullaney. Marcia's date happens to be with Warren, but based on Greg's comments, she figures that she will still go out with him since it is solely Greg who has a gripe with Warren. She however plans on not telling Greg. Greg does find out that Warren is Marcia's date, and he forbids Marcia from ever going on a date with him again.

Although she was never planning on going out with Warren again because there was no "spark" between them, she decides to ask him out again solely to show Greg that he can't tell her what to do in this matter. Greg has what he believes is his own scheme to get even with Marcia. Marcia and Greg finally come to a realization that who they are ultimately hurting by their actions is not each other. Meanwhile, Ryan, Winnie the Pooh, Kids World's Adventures Team and the kids are all excited by the upcoming junior high carnival and their contribution to it: a dunk tank.
