HelloGiggles reports that during the show's "Singalong Live" segment, one woman was surprised to learn she'd been belting the lyrics to "I'll Be There for You" wrong her whole life. She thought the chorus went, "I'll be there for you, when the rain starts to fall" when it's actually "when the rain stars to pour." Her reaction was quickly mirrored on Twitter a dozen times over. Apparently, there are a lot of fans who've been singing this song incorrectly. Below, just a few people who are shaken to their very core.
