Charlie and Joe Gass were part of Pear-Shape's criminal organization. Joe had light hair, and Charlie had dark hair and smoked cigars. The brothers had been involved with Pear-Shape's theft of jewels from Mary Waldo, as well as his selling them to an unnamed fence. A year later, the men tried to burgle the now-deceased fence's house to find the hidden jewels. The first attempt resulted in Pear-Shape being bitten by Mugg the dog on his posterior.
