Oh no! It seems that my particle has gone and gotten entangled with another particle. Now I have two of everything, and nothing makes sense!
Why did I even bother with quantum mechanics? I just wanted to make things complicated, didn't I?
Don't worry, it's not all bad! Entanglement can be a real trip. Want to see some entanglement symptoms for yourself?
Or maybe you'd like to explore some quantum fluctuations?
Or perhaps you're just here for the Schrödinger's cat.
