Is it possibly to remove the built-in pourer on a Dewar's bottle?!

I finished off a normal sized bottle of Dewar's last night.
I have a whole handle of Dewar's now, but I'd really like to pour some of it into the other (smaller) bottle since its much easier to our and is a lot "classier" than bringing a jug out to guests lol

Is this possible? I'm having a really hard time with it...
