Security guard answers phone: Security, uh Norm, Norm speaking.

Date: Norman? This is Mr. Eddie Vedder, from accounting. I just had a power surge here at home that wiped out a file I was working on. Listen, I'm in big trouble, do you know anything about computers?

Norm: Uhhmmm... uh gee, uh...

Dade: Right, well my BLT drive on my computer just went AWOL, and I've got this big project due tomorrow for Mr. Kawasaki, and if I don't get it in, he's gonna ask me to commit Hari Kari...

Dade proceeds to get Norm to read him the number off of a modem at the TV station
