Factual error: After Archer disguises himself with Pinky Brewster's clown costume, he racks the shotgun, but no shell ejects. Okay, fine, the weapon was not loaded, now it is. When Archer, still disguised as Pinky Brewster approaches Pam and Cheryl, he racks the shotgun again. This time a shell should have been ejected, but it isn't.
Continuity mistake: Mr. Rompers crosses in front of the clowns, one in blue, the other in purple, but in the next shot of Mr. Rompers the blue and purple clowns have disappeared.
Continuity mistake: The long shots of Mr. Rompers show the party guests standing with their hands at their sides, but other shots show the guests on their knees and their hands on their heads.

Continuity mistake: While clumped together at the party, Cyril, Ray, and Pam are either standing elbow-to-elbow with each other or overlapping each other as the shot changes.
Continuity mistake: A couple at the party are drinking and change positions, they are either behind Ray and Cyril's shoulders, disappear, or show up over Pam's right shoulder.
Continuity mistake: During the conversation with the others at the party, Archer walks up to Pam's right side. The immediate next shot and he is slightly in front of her.
Continuity mistake: At the party, Pam is holding the snack tray at shoulder level. When Archer walks up to her, the tray is at her waist.
