In Loving Memory Of The "Survivor" Auction

Okay, some questions here:

1. Are those...actual Doritos? I believe they had a plain flavor in 2001 (discontinued in the US in 2019), but why not use generic tortilla chips?

2. Is this spon?

3. Was spon so early in its inception that Doritos would seriously PAY money to put four of its most boring chips in front of all of America instead of a full bag of Cool Ranch?

4. Did they pay extra for Jeff to say, "These are the real deal, Tina, I know how much you love Doritos." If so, it backfired, as she responds, "I do, but that's more than $10 a chip."
