Does the Mole speak Spanish?

Would someone (can someone) explain to me the appeal of reality TV shows? "The Mole" (ABC) involves a group of mostly youngish Americans, of varying though generally considerable degrees of obnoxiousness, who have been plopped down in Chile and are being made to go through a series of seemingly pointless, mildly sadistic exercises at the end of which presumably someone will be exposed as saboteur of the whole project (hence the title) and/or someone else will walk away with a lot of money. One of the contestants in the part of the show I happened to see a couple of hours ago was using his ability to speak Spanish to advantage, an ability resented by the other competitors, though the line between envy and resentment was blurry.

A game theorist might have some fun with these sorts of shows, if she or he had the patience to sit through them. Not being a game theorist, I just find "The Mole" rather boring, even if, at the particular moment in question, it was marginally less awful than everything else being broadcast.
