"The Secret Life of Walter Mitty" and Stock Characters

This is our first assignment for English 9H. We have read a variety of short stories and for the story "The Secret Life of Walter Mitty," by James Thurber, is what this assignment in based on. In the story, it represents satire and stock characters. We have to think of three examples of stock characters on t.v. or in movies and find a character on t.v. or in a movie to represent the kind of stock character.
Three Common Stock Characters:

1) The geeky/nerdy kid
An example of this kind of person is Steve Urkel on the show "Family Matters". He has huge glasses and wears suspenders that are too short. He's also clumsy and talks differently. Everyone makes fun of him because he's not like everyone else. Other people take advantage of him because they know he's just a weak nerd.
Here's Urkel!:

2) The bossy/controlling person
Marie on the show "Everybody Loves Raymond" portrays this kind of person. She usually doesn't agree with what Ray and Debra decide on and takes control of many situations. She usually tells Ray and Debra what to do and thinks her way of doing something is better than Ray and Debra's.

3) The stuck up/popular/rich girl
Regina George in the movie "Mean Girls" is the popular girl. She has authority over everyone and can control them because they let her. Everyone thinks she's the queen bee and lets her be mean to anyone who she thinks isn't as good as her. Her friends also let her act this way and whatever Regina tells them to do, they listen to her and do it.
