fix_that_shit.js

var __bind = function(fn, me){ return function(){ return fn.apply(me, arguments); }; };

function MyClass() {
  this.my_method = __bind(this.my_method, this);
  this.my_other_method = __bind(this.my_other_method, this);
}

MyClass.prototype.my_method = function(arg1) {
  return arg1;
}

MyClass.prototype.my_other_method = function(arg1) {
  return this.my_method(arg1);
}
