Continuity mistake: When Peter and the rest are at the bar and Quagmire is telling Peter that he looked through his garbage, Quagmire's mug tops up between shots.

Continuity mistake: After Peter and Chris have the race to the 'Marker where that girl...', Peter is on the left of the cone, but when the hand comes out, he's on the right. (00:01:40)
Continuity mistake: During Kiss's performance, Paul Stanley (the one with the star face paint) and Ace Frehley (the one with the grey face paint), swap places multiple times.
Fifteen Minutes of Shame - S2-E12
Continuity mistake: When Peter puts his brush to the paint, you can tell that he dabs it in green or yellow paint, but when he paints the woman's blouse, it is red paint. (00:00:25)
Fifteen Minutes of Shame - S2-E12
Continuity mistake: The bush that the artist is painting in the pre-credits scene changes between shots. (00:00:10)
Continuity mistake: When Death is incapacitated and Peter is wearing the Death cloak, the stool that Death's legs are resting upon changes from having purple to brown legs. (00:16:45)
Stuck Together, Torn Apart - S3-E19
Other mistake: In the scene where Brian gets off the phone with the glue company, he says the bad news is that the substance to remove the glue takes two weeks to arrive, but the captions read seven days.
Continuity mistake: When Peter comes home from fishing his hat disappears from the side of the couch in a later shot. (00:03:40)
Continuity mistake: When the children are singing, "So Long, Farewell", as they are going upstairs they pass a picture of Lois' parents hanging along the middle of the stairwell. When they get to the top of the staircase, we see the exact same picture, but now at the head of the stairs. (00:04:20)
Ready, Willing, and Disabled - S3-E15
Continuity mistake: When Peter is stealing steroids from behind Mort Goldman's desk, he gets down on his knees to hide. In the next shot, he is standing (albeit bent at the hips).
Other mistake: When Lois knocks out the karate master, if you look in the stands, behind Peter, there is a person without a nose.
Not All Dogs Go to Heaven - S7-E11
Continuity mistake: In the part where Meg is asking Brian about God, and Brian answers he is an atheist, the camera pans out quickly, and we see an entrance to the kitchen with an air vent above it. Eventually the family discussion with Brian continues, and you see that the air vent is now gone.
Continuity mistake: During the yard sale, Lois goes outside the house but she doesn't close the door. She talks to Peter and the shot later, the door is closed.
If I'm Dyin' I'm Lyin' - S2-E9
Continuity mistake: When the crowd is outside Peter's house wanting Peter to heal them, a lady in pink comes out and says "It's him!". While she does this she is standing on the lawn, but in the next shot she is standing on the cement path. Other people in the crowd change position in this cut too.
Factual error: When Meg and Lois are in the back of a police car they escape by opening the back doors and getting away. The rear doors of a police car can only open from the outside, for obvious reasons and this escape could not be possible.
Ocean's Three and a Half - S7-E7
Continuity mistake: Before Dr. Hartman delivers Bonnie's baby, he removes a small wheelchair and places it on a cabinet next to him. After delivering the baby, he makes a funny remark about Paula Poundstone, and then he hands the baby to Bonnie. Notice that the wheelchair and the cabinet are no longer present.
Revealing mistake: During the Ozzy Osbourne scene, there is a person in the audience with no mouth. (00:16:10)
And Then There Were Fewer - S9-E1

And Then There Were Fewer - S9-E1
Continuity mistake: Just after the guests have found Muriel, there is a shot from outside the manor where we can see Quagmire's car at the back of the rest of the cars. But in the next overview shot of the manor, Quagmire's car is now in front of a red car. (00:29:30)
Chosen answer: It's a real song called "Elvira". Originally by Dallas Fraizer in '66, however, this version seems to be the Oak Ridge Boys cover version. However, the mega lesbians skip the verse and just sing the chorus after the opening line.
