Wag the Hog

Its guest stars are Robert Ben Garant as Critter, Wendi McLendon-Covey as Mudflap, Sarah Baker as Bethany, Joe Lo Truglio as Carl, Thomas Lennon as Kenny and Melissa Bardin Galsky as Candace.

Critter, the leader of the motorcycle gang "One Eyed Snakes," calls Bob Belcher, saying that he is in prison because he burned his parking tickets instead of paying them.

Critter wants Bob to sell his motorcycle on his behalf to an investment banker named Kenny, and to use the money to get him out of prison.

Linda takes care of his baby Sidecar while Bob and his children Tina, Gene and Louise bring the motorcycle to Kenny.

After Sidecar falls asleep, Linda tells Bethany what his real name is and that his father is imprisoned and his mother is in the woods.

He also noted that the episode "is so clever, because it very gradually lets Bob loosen up in a way that works primarily as a character move.

As he explains at the end to the One-Eyed Snakes, the reason he had any fun today is because he had his kids with him, and we see tangible signs of that through the episode, particularly when he starts getting into character as an eyebrow-eating biker tough.
