Chirpy Burpy Cheap Sheep - S3-E2
Revealing mistake: When Fargo brings Chris the sheep to Ted's place, Jack crashes down the stairs drunk and breaks all the poles of the banister. It's obvious all the poles have been pre-cut.
The Mainland - S3-E4
Continuity mistake: When Jack goes into the pub, it is dark outside, but when Ted and Dougal leave the caves, it is daytime, despite both scenes supposedly taking place at the same time.
Kicking Bishop Brennan up the Arse - S3-E6
Continuity mistake: As Bishop Brennan Holds Ted up against the bedroom wall after he has broken in, the crucifix behind Ted's head goes from hanging crooked to hanging straight between shots.
Kicking Bishop Brennan up the Arse - S3-E6
Continuity mistake: The first time Bishop Brennan inspects the skirting board, it is covered in black marks. The second time, there are none.
Kicking Bishop Brennan up the Arse - S3-E6
Revealing mistake: In the bit where Bishop Brennan realises Ted did kick him up the arse, he runs up to Ted's house with his cape flying right out. The attachments holding up each side of the cape are visible.
Night of the Nearly Dead - S3-E7
Continuity mistake: In the scene where the old women are grabbing at Eoin at the front door in one shot the top pane of the window on the left of the door is broken and an arm is coming through it, in another shot the bottom pane is broken and the top one is intact and arm is coming through the bottom pane and in the very next shot the top pane is broken again and the bottom one is intact again. (00:13:05)
Chosen answer: It's characteristic of someone putting on a fake Irish accent.
