What was a carrot stick of the Romans Senate

Explanation:

I have heard two stories this week of tempting carrots. Roman Carrots. Carrots are really tasty but beware when they are offered by Romans. This is the Roman way, and always has been. We are ruled over by Romans to this day, the Pope being the current Roman Emperor.The Roman method is to say Be ONE OF US. Be Roman. Roman history tells us how the Romans made offers to leaders of rebellious natives. When the leader of the rebellion has been Romanised, the rebellion crumbles. Maybe the followers of the rebellion follow their leader into Roman ways, and eventually there is no rebellion because all have become Roman.
