I had no idea

You know, I just assumed that Britain had rabbits. I had no idea the Romans brought them over. I can see the ancient Brits having their secret revolutionary meetings like in The Life of Brian.

"What have the Romans ever done for us?"

"Well, Reg, there are the roads."

"Of course, the roads. The roads go without saying."

"And rabbits. They brought over rabbits."

"OK, rabbits sure. But what else have the Romans done for us?"
