[5] "Monkey Wrench" is an up-tempo rock song, written in the key of B major in 4/4 time signature with a tempo of 174 bpm.

After a single bar of 3/4 time, the main verse enters with vocals and a choppier, palm-muted version of the intro riff.

In the video, Grohl arrives at his apartment with groceries in hand, but finds the door secured from inside by the chain latch when he tries to open it.

The rest of the band soon joins him at the door, peeking in through its mail slot, and eventually start trying to force their way in as the duplicate Grohl taunts them and spits on the peephole.

When Grohl is in the elevator heading up to his apartment, a muzak version of the Foo Fighters song "Big Me," performed by The Moog Cookbook, can be heard.
