Everyone knows you don't cross Alison (Sasha Pieterse) on Pretty Little Liars: The Perfectionists, but did you know that Pieterse is a cutthroat Jenga player in real life? TV Guide recently found out when we challenged Pieterse and her co-star Janel Parrish to a game of Truth or Dare Jenga.

While Pieterse is definitely the master when it comes to making those wooden stacks, Parrish kicked some serious butt when it came to the dares and challenges. OK, yes, it was a missed opportunity that she didn't say "Queen" when we asked her to rhyme words with teen, but just check out how many Mean Girls quotes she knows! She got the obvious ones and some really great deep cuts. (It's worth mentioning that Parrish OWNED the entire Perfectionists cast at our Who Said It? game, as well.)

Both women are obviously competitive, but our favorite part is when they showed what great friends they are. Just check out Parrish delivering some sweet lines when she gets dared to say something romantic to her on-screen frenemy. They really do love each other, you guys!

Pretty Little Liars: The Perfectionists airs Wednesdays at 8/7c on Freeform.
