"Anything Can Happen in the Next Half Hour..." (often shortened to "Anything Can Happen") is the second physical single, and third overall, by Enter Shikari and the second single to be released from their debut album Take to the Skies. It was released on 18 February 2007 for digital download and on 5 March 2007 on both CD and 7" Vinyl. Currently it is the band's highest charting single, charting at #27 in the UK single chart, and number 1 on the UK indie chart. There are two remixes of the song, Colon Open Bracket Remix and Grayedout Mix. Both are up for download on their official download store.
In the original version of the song, a sample is heard from the introduction of the popular 1960s TV series Stingray in which the character says "Anything can happen in the next half hour". This is, however, not heard in the re-recorded version.
