// this is just a really silly way of saying this 
Function.prototype.call.apply(function (a) {return a}, [1,2])
// 2

// if this still seems weird to you. Consider this: 
function logThisAndArgs(){ console.log(this, arguments); }

Function.prototype.call.apply(logThisAndArgs, [{'some':'object'},1,2,3,4])
// logs -> Object { some="object"} [1, 2, 3, 4]

// or this! 
Function.prototype.call.call(logThisAndArgs, {'some':'object'},1,2,3,4)
// logs -> Object { some="object"} [1, 2, 3, 4]
