Show your exact code. I would guess that you are passing an array of 3 
elements for args, when your class's initialize method takes only two.

Here's how it works:

>> class Foo
>> def initialize(a,b)
>> @a, @b = a, b
>> end
>> end
=> nil
>> args = ["foo", "bar"]
=> ["foo", "bar"]
>> Foo.new(*args)
=> #<Foo:0x7f0223609470 @a="foo", @b="bar">
