The Office (US) - Season 2 Episode 7 -

When Michael and Jan try to nail down a potential new client, Christian, by taking him out to Chili's, Michael surprises everyone with what - or who - he does. Meanwhile, back at the office, Jim finds a semi-autobiographical script that Michael has written called Threat Level: Midnight, and he, Pam, Kevin, and the rest of the Dunder-Mifflin workers have a great time acting it out. Later that night, Pam and Jim share their first unofficial date, complete with dinner (a sandwich), candlelight, and Dwight's pathetic fireworks display.
