Continuity mistake: When Stewie has chicken pox the red marks on his face change position many times between shots. A noticeable one is just as he is saying "No, damn you, I've got to finish what I started".
Mr. Griffin Goes to Washington - S3-E3
Continuity mistake: When Mr. Weed is crying about losing his job, we see a view of a long line of trees in the window behind him. The camera switches to a close-up of Peter. When it zooms out again, the trees on the right of Mr. Weed are missing.
Suggested correction: I watched this part of the episode twice and no trees are missing in the window behind Mr. Weed after the close-up on Peter. Actually, Mr. Weed's head is covering part of the window where you can't see the trees on the right when he's lying on the table, but when he gets up you can see all the trees.
One If By Clam, Two If By Sea - S3-E4
Other mistake: After the hurricane passes, Peter acts like he's been impaled by a wooden plank. He pulls it out as if it was attached to his right side. However, the way the metal on the clasp was bent, the only way the wooden plank could've been positioned that way is if the metal was over his shoulder.
Continuity mistake: When Joe arrives at the orphanage when he's telling his story, the sign changes position and the writing changes on it. (00:11:30)

The Thin White Line (1) - S3-E1
Continuity mistake: When Brian is saying that his family has it all wrong about his drugs, Lois is holding Stewie. In the very next shot of his family from the front, Stewie is standing on the ground, without any time for him to climb down. (00:15:10)
Boys Do Cry - S5-E15
Factual error: When Brian fires his pistol in the air, eventually killing the Super Devil, we hear six gunshots, each followed the distinct clink of the ejected cartridge hitting the ground. Trouble is, Brian is firing a revolver, which does not eject the cartridge after the bullet is fired. Only automatics do that.
Audio problem: When the English mother at the airport says "These are all ours", she says it in a posh American accent, not an English one. (00:05:30)
Factual error: When Carol gives birth there is no umbilical cord. (00:06:30)
Peter Griffin: Husband, Father...Brother? - S3-E14
Continuity mistake: When Chris says "Cool, I get to be black and Irish, he is holding three books, the top one being green. A few moments later, the top book is brown.
Other mistake: When Chris is telling Peter that he is out of the scouts, pink can be seen through his earring, even though his earring is in front of his blonde hair, not his skin. (00:06:30)
To Live and Die in Dixie - S3-E12
Other mistake: When Stewie is with his 'band' for the first time when he is tuning his guitar, the string he's tuning doesn't match the peg he's turning.
Chitty Chitty Death Bang - S1-E3
Continuity mistake: In the flashback of Lois making a birthday cake, the cake has dark pink icing on the top and light pink icing on the sides. When Peter comes in to talk to Lois, the two colors have reversed. (00:01:35)
Audio problem: When Stewie knocks his glass off the table, it makes a shattering sound, but it doesn't shatter.
Airport '07 - S5-E12
Continuity mistake: When we first see Peter lounging on the front lawn with his feet in the baby pool, there is water that has spilled out of the pool onto the lawn, but in the next shot, the spilled water is gone. (00:02:15)
Continuity mistake: When the flag team first walks out to the field, they are all in a straight line. Next time they are in two seperate lines with Meg at the head. Also, the girl with the head brace moves to the front when she is seen in the back. There is not enough time for them to move into the lines. (00:06:50)
Continuity mistake: When Lois is talking to her father about Peter wanting to be friends with him, the two emblems on Carter's shirt disappear between shots. (00:07:55)
Chitty Chitty Death Bang - S1-E3
Continuity mistake: When the Cheesie Charlie's worker walks away from Peter there is no game on the right of the 'Outlaw' game, but in the next shot, there is. (00:07:30)
