The show's host, Jeff Probst, insultingly passed this off as a reward for the tribe that successfully completed the day's challenge, rather than as a general punishment for all of humanity. So the winning tribe went to the Survivor: South Pacific Cinema (how did they survive with only one cinema?!) and the contestants got to sit back and absorb some of Sandler's wacky hijinks.
The captive audience really seems to enjoy the funny voices and frequent pratfalls, judging by their raucous laughter. Like this guy ...
And yet his cup looks like it came from the neighborhood deli. Coke wouldn't bite, eh, CBS?
... who is laughing uncontrollably at the scene where Sandler's Jill character appears for the first time. This is especially notable since that scene had no jokes and wasn't meant to be funny. He's laughing at the setup to a joke -- that's like cracking up when somebody says "two men walk into a bar." Why, we're starting to think something on this Survivor show might have been staged!
Wait, does that mean they never really set fire to a mass grave?
