The album's opener, "Doll", involves the fear of entering into situations unprepared. Regarding "Monkey Wrench", Grohl stated that it was "a song about realizing that you are the source of all of the problems in a relationship and you love the other person so much, you want to free them of the problem, which is actually yourself. It was a riff that turned into another riff that turned into another riff and ended up being a nice little power punk song." In another interview, Grohl stated his pride in the song: "With Monkey Wrench I remember I had the main riff, but I didn't have the little jangly riff that goes over the top of it and I thought it needed something. So I came up with the jangly riff and thought 'Oh my God this is never gonna fly! Everyone's gonna hate it'. But I was really excited the first time I heard it on the radio—it was in the middle of a load of mid-'90s grunge shit and I thought it was so killer." The song was released as the first single from the album in 1997.
