"Can We Fix It?" is the name of the theme song, written by Paul K. Joyce, from the children's television programme Bob the Builder, produced by Hot Animation. The song's title is derived from the main character's catchphrase. The chorus of the song features this phrase prominently, as well as the response, "Yes we can!"

"Can We Fix It?" became a Christmas number one single in 2000, beating Westlife's "What Makes a Man". It was the biggest selling single of the year in the UK, appearing 80th in the all-time UK best-sellers list. It reached number one in Australia in 2001.

A second single by Bob, "Mambo No. 5", with the lyrics adapted from Lou Bega's 1999 hit version, also reached number one a year later. An album entitled The Album followed, which debuted at No. 4 in the UK Albums Chart, and included a cover of Elton John's "Crocodile Rock".

"Can We Fix It?" was voted 42nd by Channel 4 viewers in November 2003 as one of the 100 worst singles of all-time, despite the song reaching No. 1 in the UK. Additionally, many people had covered this theme several times to celebrate a special tribute to the show.

Nonetheless, the song was rated 8/10 by Stylus Magazine, saying "kids TV themes getting to number one is a thing to be savoured, especially when a) it stops pretentious tosh like "Stan" from reigning at the top of the charts b) when it actually has a much better 2-step beat than any of the garage number ones from the previous 18 months."
