"One Week" is a song by Canadian rock band Barenaked Ladies released as the first single from their 1998 album, Stunt. 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, where it topped the Billboard Hot 100. Coincidentally, when the song reached 1 on the Billboard Hot 100, it remained in the top spot for one week. In Canada, "One Week" reached No. 3 on the RPM Top Singles Chart, while worldwide, the song peaked within the top 10 of the charts in Iceland and the United Kingdom. The band has not equaled this level of US chart success since, though singles "It's All Been Done", from the same album, and "Pinch Me", from their subsequent album Maroon, both broke the top 50 of the US Hot 100. Apple used the song at MacWorld 1999 for presenting Mac OS X Server on a wall of 50 iMacs. History Ed Robertson wrote the ideas for the non-rap "choruses" with the concept being the structure of a fight between a man and a woman where the protagonist knows he is wrong and is just trying to save face. Robertson wanted to come up with a rapped verse for the song but all attempts failed. Bandmate Steven Page suggested he simply improvise the rap, as the two did onstage every night. Robertson heeded the advice and set up a video camera. He improvised the song at a slower pace to make rhyming easier and arrived at about four minutes of rap. He sent it to Page, who told him not to change a word. Two minutes of the improvising was almost directly compiled (with very little, if any, tweaking) into the verses of the song. Due to its improvised nature, the rapped sections are not intended to have any direct relation to the plot of the sung sections. The lyrics in the liner notes from Stunt contain some additional lines of rap that did not make it into the recorded version. Band members have stated that the first live run-through of "One Week" did not go well and that it took some time to get the song
