Jim and Darryl aren't getting along in Philly because Jim is a slob and Darryl is a neat freak. Someone painted butts on Pam's mural, so she gets Dwight and Nellie help her solve the crime. They find out it was Frank, so Pam and Dwight paint on his truck. He goes after Pam and Boom Mic Brian close lines him. Brian and Frank both get fired, but the former tells Pam she can call him if she ever needs anything.
