Honest opinions

TESTER: So, prior to the focus test, we just want to get to know you a little before we show you the product.
GREG: Yeah, I've done these. The product's great.
TESTER: Well, I haven't shown you the product.
GREG: But I bet it's great.
TESTER: OK, but... you don't have to like it. We want your honest opinions. Positive or negative.
GREG: Well, I'm positive it's great.
TESTER: Sir, you don't even know what it IS.
