Mr. O'Neill's Class (Part 1)

Some of this confirms previous guesses at who is named what, but new material will be added.

In the first picture above, from "The Misery Chick" (showing exactly the same class arrangement as in "Cafe Disaffecto"), we have from left to right: Jennifer, Brittany, Bob, Jennifer.

The second picture, from "A Tree Grows in Lawndale" (once again showing exactly the same class arrangement as in "Cafe Disaffecto"), we have from left to right: Jennifer, Zack (previously hidden behind Brittany's head), Jennifer, Jennifer (Burnout Girl), and Kelly. Bob is now hidden behind Brittany's head.

The last picture, from "Cafe Disaffecto," is: Josh.
