• The origins of this song lay in a mispronounced word. Weezer frontman Rivers Cuomo explained to Spin magazine: "'Where's My Sex' - I can't remember now, if it was my two-year-old daughter that said it, or my wife said it, or my wife told me that my daughter said it - it was one of those three things. One of them accidentally said 'Where's my sex' instead of 'Where's my socks' - they couldn't find their socks. And when I heard them say 'Where's my sex,' I just thought, 'That's a cool song title right there,' so I went and just started writing like crazy. And I wrote all the lyrics. First, I wrote it all about socks, like the song is all about trying to find your socks and how terrible it is when you're not wearing socks. And then I just went back and changed a few letters in the word and it became a totally different animal."
• Cuomo described this track to the NME as "psychotic." He explained: "I sound like a crazy person. It's a side of me that came out in the song."
