Just a formal description working well to describe the deep nucleon interaction? 1/3 elementary charge is very suspicious! Do electrons "exist" within an atom, or are they "created" when I ionize an atom? This question is borderline for electrons, but maybe the analogon is closer to truth for quarks.

He seemed to be implying it's impossible to ever remove a quark. But if you smack a proton hard enough the quark does leave, only it makes a little friend to keep it company.
