• Bassist James Johnston told XFM radio about this song, which concerns misplaced trust: "It's pure Pop perfection, we really wanted a song that was really bouncy and in its essence a real Pop song. Its simplicity is what makes it a great song, everyone can sing along to it. I think that's what makes us interesting as a band, the ability to explore different types of music. It's miles away from our last single ['Machines'] and hopefully people will enjoy it for exactly that reason."
• The CD B-side of the song's single release featured an acoustic interpretation of Rihanna's "Umbrella," taken from their session for the Jo Whiley Live Lounge on BBC Radio 1.
• The director Tim Mattia told the New Musical Express January 19, 2008 about the video: "It wasn't a high-concept video, we just wanted to capture them in a moment of time. 2007 was Biffy's biggest year so far - the album's done amazingly well and they've been everywhere - so the idea was just to film them on their victory lap. The gig was at Brixton Academy and there was a real 'I was there' kind of atmosphere. I think all the front row had 'Mon The Biffy' written on their faces in marker. I was with the band for the whole gig and I noticed how ritualistic they are, especially before they go onstage. They practice their singing together and there's a lot of hugging too. They're obviously very close as people and I think that bond is part of why they're such a good band."
• Puzzle was named the 2007 Album of The Year by the Kerrang magazine.
