Answer: It was mainly done to intimidate Stewie and show Stewie how crazy he is and how tough he is. There's a similar scene from "Lethal Weapon" where Mr. Joshua puts his arm over a guy's lighter to intimidate him and show how he's impervious to pain.

Answer: There are companies in real life that will let you name stars after someone as a gift (although the star name won't go on any official government registry). You pay a company (in Peter's case for $50) for this privilege and they'll send that you information where the star is located. Mort is then looking at the star named after him. But it's as useless of a gift as you can imagine since it doesn't really mean anything and you can't do anything with it and Mort knows Peter spent money to do it. Mort would rather have had Peter just give him $50 cash as a gift. One could say it's a joke about the stereotype that Jews love money, but in this case a lot of people would rather have money over a useless gift.

Answer: It's just a joke about what an ordeal it is to move Joe around when he's not in his wheelchair.

Answer: It's an exaggeration of using electric sex toys because Joe can't have regular intercourse because he's numb from the waist down.

Answer: Joe and Bonnie are getting intimate here I believe. It's showing what an ordeal it is for Joe to have sex, since paraplegics basically can't.

Answer: It's a joke about how Rita's so old the number on her bracelet wasn't a 7-digit number. In the early 20th century to place a call you could call "Central" and tell the operator "Murray Hill 4185" and she would connect you. Rita is telling Brian to call the operator (dial "0") and read "Murray Hill 4185" to Sarah, the operator.

Answer: Because the peanut butter would get stuck to the roof of his mouth. Then as he's trying to lick the peanut butter off, he'd be constantly opening and closing his mouth.

Bishop73

Answer: There's an old show called Mr Ed about a talking horse. They used peanut butter in the horse's mouth.

Answer: If you've ever seen a dog eat peanut butter, you'd see how it looks like they are talking since it's so sticky.

Cheyenne Williams

Answer: He was saying he's paying the cable bill but Stewie said Peter pays the cable bill. Brian's reply is that the cable he's paying for is for a girl. It seems he's kind of embarrassed to say it and so it seems the bills he's paying aren't his but a girl he's dating (although somewhat implied that she's using him).

Answer: So he doesn't get vomit on them. It's a joke on how people with long hair would have someone hold their hair.

MasterOfAll

Answer: It's just a humorous riff on women who are about to vomit asking their companions to hold their hair.

Michael Albert

Answer: It's long been a running joke that Meg is unpopular; Stewie meant that now Meg will be busy with her flag girl duties rather than at home where presumably no boys will be calling for her.

Answer: There is an old stereotype that people on the flag team, or (at some schools) the "color guard", were not good enough for the cheerleading team. "Losers", "dorks", etc. Meg thinks that joining the flag team has finally made her popular, but Brian and Stewie are aware of the stereotype. Stewie is saying that nothing much has changed; she simply has a new activity, where she will be the same "loser" type.
