Almost two decades since the release of 'One Week ', a song by the Canadian rock band Barenaked Ladies, and is 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.

Coincidentally, the song reached #1 on the Billboard Hot 100 for one week.
