Jack Deforest is a student at Springfield Elementary School.

History
At the school's audiction for a play, Lisa got the role of Ilsa, and Milhouse tried to audition as Rick so they could be the main couple of the play. However, when Chalmers was going to make the decision final, Jack entered the audition and got the role.

Bart, realising only the two auditioned for the role, if Jack couldn't perform the character, Milhouse would get the role, and hired the bullies to beat him, but Jack defeated all of them. When Skinner saw the fight, he gave Milhouse back his role, much to Lisa's dismay as Milhouse was a terrible actor.

At the play, Milhouse performed perfectly, but it's revealed it was Jack pretending to be Milhouse playing the role.

At the end, he and Lisa went out for a float together.
