In this episode, Peter is revealed to be an illegal Mexican immigrant. But Thelma is an American who gave birth in Mexico, she was on vacation when she gave birth to Peter, so Peter should still be a United States citizen.

In this episode, it is revealed that Peter was born in some kind of barn in Mexico while his mother was trying to get an abortion. However, in "And the Wiener Is..." when seemingly about to be killed by a bear his life flashes before his eyes. This flash back shows him to be born in a hospital.

When Carter Pewterschmidt saw the illegal immigrants celebrating Cinco de Mayo he stopped them and forced them to go back to work and they understood everything he said.

There are a couple of inconsistencies with Lois and Stewie's injuries during the fight scene.

When Stewie is hit with the vase, his hands are bleeding. The blood disappears when he's playing with the pins from the grenades, but then re-appear when Lois surrenders.
A scratch on Lois' left cheek mysteriously appears when she starts attacking with the pole. When Stewie starts using a flamethrower, the scratch has gone again.

When Stewie forces Brian to drive away from the house, the sound of the engine turning over can clearly be heard. However, because of the way that the engine is designed, a Toyota Prius has a silent ignition.

During the battle between Lois and Stewie in the oval office, the presidential portraits can be seen on the wall. Bill Clinton appears naked in his portrait.

Ringo Starr did write or help write a few songs for the Beatles. One of his songs was Octopus Garden, co-written with Harrison.

Stewie fires about 10 shots at Lois before the shot switches to Lois, who only has 4 bullet holes in her. Than after they switch to Stewie and back again, the bullet holes are in different places. On top of that, as she falls over the guard rail, she has only one visible exit wound, but suddenly has 5 more as she's falling, and the wounds have moved around again. Also, while Lois was sinking, you could clearly see that she had no exit wounds in her back, even after seeing the bullets pass through her when Stewie shot her, and when you could see them when she was falling off the boat.
