Quick question Have we ever in our history done the double

Quick question Have we ever in our history done the double over the wurzels and the jacks in one season do u know ?

Trick question

Never done the doube over the jacks (until this season).

Don't get it???

We might have beaten the jacks twice in one season but it’s still not a double. A double has to be in the same competition and once home and once away
