Continuity mistake: When Andy Konsong discovers his brother's mutilated body in the bloody swimming pool, he vomits, then tries calling for help on his cellphone. As he makes his call, the gigantic crocodile lunges out of the pool and bites off Andy's arm, cellphone and all, above the elbow. Andy screams, staggers and lands on his back, but his only injury thus far is his severed right arm. His mouth is not bloody at all, nor should it be. The camera cuts to another angle as the crocodile lunges a second time; but, before it even enters the frame and bites into his legs, Andy's mouth is suddenly full of blood, his teeth are bloody, and blood is streaming down his chin, even though he has suffered no abdominal injuries.
Continuity mistake: When Stan is asking his wife to use the dildo on him, you can see it changing direction between shots. (00:17:25 - 00:18:00)
Continuity mistake: In the 2nd meeting between Emily and James, she brings him supplies. Emily is seen twisting at the cap on the bottled water before handing it to James. However, when she hands it to him, the cap is visibly still on the bottle. James is then seen removing the cap himself. He sets the cap on the table, takes a drink, then puts the bottle on the table. The next shot shows Emily with her hands in her lap then reaching for the bottle and putting the cap back on as if the cap was already in her hand. She never removed he cap. The cap would still be on the table where James put it. There is no way she could have retrieved that cap off the table without coming into camera view.
Continuity mistake: When Larry says, "Gitr Done", he is holding an M60, yet when he then runs to the Humvee he has an M16 which is noticeably smaller.
Continuity mistake: When Frylock is watching New Jersey getting destroyed by the Insane-O-Flex, look for a building to the left through the Ferris Wheel. When Meatwad transforms into a building, the fires briefly stop, then turn on again.
