Another hilarious episode. I loved the robot. Too funny.

Here's what I think the remaining schedule is:

Episode #5: So You Think You Can Dive: 5 left, down to 4 by end (Seems likely to feature the show's Apprentice parody)
Episode #6: The Amazing Disgrace: With only 4 left, this is the last chance to have teams of two. My guess: one loses at the finish line with the winning team choosing one of the losing team to eliminate

Remaining are Hunting With The Stars and what looks to be something involving American Idol/Hell's Kitchen or Idol/Survivor?
