On Guerrilla Warfare Puns

In my biology class not too long ago, we covered a mini unit on invasive species. One of my classmates was giving a presentation on an invasive monkey species, explaining how it is very aggressive in nature and has been known to attack people and other animals in small groups. After hearing this, I couldn't help but raise my hand and pose the question: "So you could say these monkeys use guerrilla warfare?". Almost the entire class groaned simultaneously. It was glorious.
