TV Guide - The Office - 10,000 Minutes
Summary: Over 10,000 extra long minutes until next week's The Office.
The ad is presented as white text on a red background, and keeping with an office theme, the words are typed like they would be to a computer screen. The text is modified to read "Over 10,000 extra loooooong minutes until next week's The Office."
The kicker is "(That's what she said.)" This is character Michael Scott's favorite joke on the show, a traditional sexual innuendo follow-up to an otherwise innocent statement.
