Traffic spike effect

CHRISTINA: Well, our site's traffic has returned to normal, and it looks like about 100,000 people downloaded our demo.
RONI: That's AMAZON! JOHN: What's the point? They CAME and they LEFT. We got ZERO mailing list signups...
JOHN: And we sold ZERO t-shirts. CHRISTINA: Actually we sold TWO t-shirts. DAN: No, I bought those two.
JOHN: Great! We sold NEGATIVE two t-shirts... DAN: Hey, is there a way for you to not, like, cash my Paypal thing until Friday?
