Use $.extend() for prototypal inheritance?

Question

Maybe this is a crazy question, but something like:

var MyPrototypeObject {
    prop: 0;
};    
var ob1 = Object.create(MyPrototypeObject);
var ob2 = { 
    meth: function() { 
        this.prop = 5; // update prop 
        return this.prop;
    }
};

where Object.create clones the prototype and $.extend is used to add additional methods to ob1, where this.prop points back to the prototype? What's the best way to add new methods?

$.extend(ob1, ob2);

pd-style is similar and recommends

var SomeProto = {
    prop: 0;
};    

var ob1 = extend(Object.create(SomeProto), { 
    meth: function meth() { 
        return (this.prop = 5); // update prop 
    }
});

This is an effective way of handling OO in JavaScript. Note that $.extend is a shit implementation for doing this because it has an isPlainObject check which returns false for objects that have prototypes
