Phoebe finds a comic book in Jake's room stored in a comic toploader, which is a hard plastic sleeve with an opening on the short edge, used to protect a single comic from bending, tearing, edge and corner damage. In order to get the comic out, she "breaks" it open, complete with a glass shattering sound effect. Again, it's made of plastic, not glass, and is made with an opening on one end. There's no need to break it open, and you certainly wouldn't hear glass breaking if you did. See more
