On "Pretty Little Liars," Spencer (Troian Bellisario), Hanna (Ashley Benson), Aria (Lucy Hale) and Emily (Shay Mitchell) are constantly dealing with death, blackmail, insane asylums -- you know, typical high-school drama.
But behind the scenes, the actresses and their co-stars have tons of fun on set, as you can see in the bloopers from "Pretty Little Liars" Seasons 1 to 3 above.
From disruptive creepy, crawling critters to a sex scene that almost went too far, watch the gag reel to see the laughter and light-heartedness that goes on behind the twisted teen show.
"Pretty Little Liars" airs Tuesdays at 8 p.m. ET on ABC Family.
