Whoever did the subtitles made a mistake...and obviously doesn't watch the show. Lea Michelle (as Rachel) is talking about how much she love Barbra Streisand and "Don't Rain on My Parade." She says "My dads played it for me when I was in my birth mother's womb." Except the subtitles are: "My dad's played it for me..." Rachel (the character) has two dads AND the possessive isn't grammatically correct. It's not as bad as the "West Side Story" goober, but where's quality control when you need it?
