"I hate 'A' moments, I really do. They irritate me," says Troian Bellisario (Spencer). "Don't give 'A' triumphant moments. That's like the end of every episode for us."

While we certainly feel Troian's pain, we're more inclined to think "A" moments are awesome. Whether they're thrilling, creepy, or downright terrifying, the creepy stalker's evil machinations set the show apart from other high school dramas.

In this video, the cast takes us on a walk down memory lane with their favorite "A" moments. So watch the video to find out what scene scared Shay Mitchell (Emily) while she was filming it, which moment Keegan Allen (Toby Cavanaugh) can't get out of his head, and more.

 

Find out who “A” is on the Pretty Little Liars Season 2 finale on Monday at 8 pm ET/PT on ABC Family.
