Gilly is an elementary school student who is played by Kristen Wiig. She is known for being mysteriously disobedient, often doing elaborate and sometimes violent things without anyone in the class noticing. Often, her teacher accuses other innocent kids in the class of doing the things that Gilly does. When the teacher finally accuses Gilly, she smiles and says, "Sorry."
