The text is a play on the phrase 'Guns don't kill people, people kill people.' It replaces 'kill' with 'soak' to humorously adapt the phrase to the context of squirt guns, which are designed to squirt water. The humor arises from the unexpected substitution of the word 'soak' in a well-known saying, rather than from a double meaning or similar-sounding words.
