These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Tourettes Guy
Broken Base: The 2004-2007 episodes versus the 2009-present episodes.
WOF's family-friendly television standards do not permit swearing. The handlers of the contestants probably did a background check on him and that's all she wrote. Even if it did happen, that episode would probably never be allowed to air... and likely show up online instead.
Unfortunate Implications: Defied. The creators were fully aware of the implications of Danny's behavior would be. As they point out on the main page, Danny is often seen drinking heavily on-screen and his insane behavior probably has more to do with that than any actual disorders he has.
