My Name Is Earl - Season 4 Episode 3 Joy in a Bubble

Earl's attempt to give Joy the hot tub she's always wanted backfires and she is forced to stay in a makeshift bubble because of a flesh eating toe infection. While she is out of commission, Earl must fill in as the new Joy. Between gossiping with the ladies at the salon and shopping for meat out of some guy's trunk, Earl learns about the Turner family. This includes the fact that Dodge and Earl Jr. might have a social disorder that causes them to have no friends. Can Earl fix this problem too?
