The real science
When a splinter lets bacteria into your skin, a white blood cell called a neutrophil follows a chemical alarm and squeezes out of your blood vessel to swallow them. When there are too many bacteria, it bursts and throws out a sticky net made of its own DNA. The yellow pus in a pimple is mostly dead neutrophils like this one.
