Great/hilarious episode,
The highlights:
Stewie looking awesome in a gold suit, hahahahahaha.
Lois torturing Peter/Chris grocery gag, hahahahahahahaha

.
Lois trolling Peter in a dress, hahahahahahaha, Lois's jerkiness cracks me up, since Lois has become a horrible hateful person worse than Peter/Quagmire/Carter, the people do want Lois to be killed off alright.
The Beastmaster reference/scene, awesome, the movie references/gags/showings in the show get
EPIC by the minute.
Iguana Peter gag, hahahahahaha.
Peter getting a vestigial twin, random/weird/sweet, but I love Chip who's a great funny minor character with a Mickey Mouse-ish voice, hehehe.
Chip providing good help on controlling the bear.
George Washington joke.
Peter hating Chip and wanting him removed, hehehe.
Peter the handbag, hahahahahaha.
Stewie's Sorry!, hahahahahaha.
Chip separated and being a new Griffin Family member, sweet, Chip looking a small nicer/kind Anti-Peter Griffin, hehehe.
Chip doing the opening
Family Guy theme and Peter being a big crybaby, hahahahahahaha

.
Peter being at his worst like always in his jerky ways to get rid of poor Chip.
The dog attacking Peter and kidnapping poor Stewie, hahahahahahaha.
Peter broked his leg, the Peter bashings are always satisfying, he always deserves it, hehehe.
Chip saving Peter.
Farewell Chip and joins in
The Middle(my favorite funny comedy along with Axl being a great funny obnoxious selfish jerkbag), hahahahahahaha, I'm glad he's a good guy throughout the episode and not a sadistic villain, I hope he makes a future return.
