It was written by Ed Robertson, who is featured on the lead vocal of the rapped verses . Steven Page sings lead on the song's chorus, while the two co-lead the prechoruses in harmony . The song is notable for its significant number of pop culture references, and remains the band's best known song in the United States . Coincidentally, the song reached #1 on the Billboard Hot 100 for one week . </P> <P> "One Week" is the band's best - performing single on the charts in both the U.S. and the U.K., though it slightly under - performed several other singles in the band's native Canada . It was the band's only number one single in the U.S. on both the Hot 100 and the U.S. Modern Rock Tracks (for five non-consecutive weeks). The song spent seven weeks at number 3 on the Hot 100 Airplay and an additional four weeks at number two behind the Goo Goo Dolls' "Iris". The band has not equaled this level of U.S. chart success since, though singles "It's All Been Done", from the same album, and "Pinch Me", the first single from their subsequent album Maroon, both broke the top 50 of the U.S. Hot 100 . Apple used the song at MacWorld 1999 for presenting Mac OS X Server on a wall of 50 iMacs . </P>
