You know that there's something wrong with the world when that's the title of an episode of Maury, and it's totally not a joke. Like, they treat the subject as seriously and legitimately as any of their other subjects. Let me just ask this: Who in the world is afraid of mustard??? "Aaah! There's a tasty, tangy condiment coming towards me! Oh noes!"
Favorite part of the show: when a helper brings out a tray just heaped with a mountain of gloppy mustard, and the guest runs screaming into the audience.
