Java

Let's play with Java class loader:

    import java.lang.reflect.Field;

    public class Loop {
	    public static void main(String[] args) throws Exception {
		    System.out.println("Let's loop");
            Field field = ClassLoader.class.getDeclaredField("parent");
            field.setAccessible(true);
            field.set(Loop.class.getClassLoader(), Loop.class.getClassLoader());
        
	    }
    }

This loop is actually so strong you'll have to use a `kill -9` to stop it :-) 

It uses 100,1% of my Mac's CPU.

![100,1% of CPU][1]

You can try to move the `System.out` at the end of the main function to experiment an alternate funny behavior.
