Han Solo: Fast ship? You've never heard of the Millennium Falcon?

Obi-Wan "Ben" Kenobi: Should I have?

Han Solo: It's the ship that made the Kessel Run in less than twelve parsecs. I've outrun Imperial starships. Not the local bulk cruisers mind you, I'm talking about the big Corellian ships now. She's fast enough for you old man.
