Oh, yeah, it was the orc chief. Here I was thinking that that was what Pippin said to the ruffians.
Hehe, I think like that scenario better:
Ruffian: Move along, move along.
Hobbits: We will go just as fast as we please.
Ruffian: You're under arrest, you know.
Hobbits: If you don't watch it, we'll give your name and number to the Nazgul!
