Not as much terrified, but more like "I have seen something that shouldn't have aired on TV, and now I'll spend the next few moments curled up in a fetal position in a corner attempting to gouge my eyes out and pour brain bleach down them while babbling like a mad man".
As my sister, mom, and I were setting up our Christmas tree, for some reason they were watching I think it was the Wendy Williams Show (nothing else was on apparently). Anyway (and I know this'll be on The Soup in a heartbeat (say next episode that airs (You HAVE been warned))) after a performer was interviewed, he started singing another song (probably from a new album or something; very 80s sounding. Maybe a re-release), and everyone was dancing or doing a dance competition; first a flamboyant dancer, then another, then another... and then out of nowhere, an elderly couple (married for 60 years according to the interview with them after the dance) were dancing like you'd see some people dancing in a nightclub during Mardi Gras.
I've got a couple shots of hot sauce laced with cayenne pepper and garlic juice to pour in my eye sockets right now to try and remove the image from my head. Seriously, the deepest darkest parts of Hell look like paradise compared to what I saw. My God, what did I do to deserve such torment?
Itnetlolor has gone stark raving mad!
EDIT:
And if someone already uploaded a clip onto Youtube, I advise against looking for it. You'll just end up like I did. Blind and in pain with a horrifying image burned in the retinas.
