Trading Spaces: The Con is On

I've been seeing the promos for this week's upcoming episode. Basically,
it's Trading Spaces meets Punk'd, minus Ashton Kutcher.

Have the ratings taken another plummet so that they are reduced to using 
MTV tactics?

I don't know whether I would watch out of morbid curiosity to see Hildi 
and Doug take it on the chin, or just assume that it's all scripted and 
faked.
