Mugger

"Whatcha been up to? Livin' in fear?"

- The mugger, after running into Marge a second time

The mugger is an unnamed criminal who stole Marge's necklace. He wears a trenchcoat and a Goofy hat.

History
When Marge and the kids had to drive home from Rainier Wolfcastle's house, she met a mugger on the way who stole her necklace and ran off. The mugger caused Marge to feel weak and become too afraid to venture outside her house. After building her confidence through weight lifting, however, Marge is soon able to overcome her fear and face the world once more.

She later gets a shot at redemption when she is confronted by the mugger a second time, and beats him to a pulp in front of a crowd of onlookers.

During Trappuccino he was among the townspeople when they were trying to break out of the dome.
