The series takes its title from the song of the same name, which was originally released on a hit record by The Romantics in 1980; it was written by the group's members Wally Palmar, Mike Skill, Rich Cole, and Jimmy Marinos. A cover version of the song, performed by the Canadian all-female rock group Lillix, was used as the theme song for the show. Lillix's cover version was also heard on the soundtrack of the 2003 remake of Freaky Friday and the soundtrack of the film 13 Going on 30. The theme was remixed into a techno/dance style theme for the second season by Philip Steir (who composed all the music for remainder of the series).

The pilot episode had a short opening sequence and the cast members' names were only shown over the cold open. The title sequence used scenes of New York as a background, with an animation of the show's logo in which the letters "i" and "o" appeared first in a larger size than other characters, the word "what" slid in from the left side of the screen, the word "like" expanded and contracted, the "ab" and "ut" in "about" slid in from both sides of the screen to meet the "o", and the word "you" slid upward from the bottom of the screen, appearing to collide with the rest of the title before all the characters settled into place. This same animation was carried over to the season one opening titles.

The first season's opening sequence featured intercut scenes (as from home movies) of two girls portraying younger versions of Holly and Val, with shots of Bynes and Garth sticking their tongues out at the camera, mixed with footage excerpted from the first four episodes; each of these elements were framed in rounded rectangles that moved from right to left across the screen. After every two to five such rectangles, the headshot of each cast member would appear with its name. Newer footage excerpts were inserted in the sequence for the episode "Valentine's Day" and again for the episode "The Fix-Up", which replaced nearly all of the excerpts from the first four episodes.

The opening title sequence used for the rest of the series featured the show's cast in front of digitally inserted scenes of New York at night. Different versions of the sequence were used for SD and HD broadcasts: the SD version seen in The WB, TeenNick and until October 6, 2010 in ABC Family airings, featured a letterbox-style version with the cast and creators' names in a black bar below the sequence; HD broadcasts on The WB and in ABC Family airings since October 6, 2010, featured the cast and creators' names within the sequence itself. The sequence was modified twice; the first time was in the episode "The Incredible Shrinking Group" when Stephen Dunham's video headshots were removed and the second modification was in "The Longest Night of the Year" when all traces of Michael McMillian were removed from the sequence and a yellow streak of light was added to the sequence as well.
