2:05 We will move out. We will move fast.
2:07 And if necessary we will push back.
2:10 The only thing that matters now
2:12 is getting the merchandise to the customer.
2:18 Let’s see if you’re worth the money.
2:20 You don’t need to baby-sit me.
2:22 I baby-sit everyone.
2:24 That’s kinda my thing.
2:38 What the —
3:04 They’re moving in. You got six on your tail.
3:06 Xavier, do me a favor.
3:07 Push ‘em back a little bit.
3:24 This is your world?
3:27 Have you never seen it before?
3:28 Drive the car.
3:29 Not with my eyes, no.
3:30 Five. Shut up.
3:32 But I know all about your world.
3:33 Really?
3:34 Do not communicate with the specimen...
3:37 - Alaska has a longer coastline... - Five...
3:39 - ...than all other 49 states combined. - Stop talking.

4:37 Okay.
4:38 Do you have any idea what you just did?
4:48 I might be a little rusty right now,
4:50 but I’ve been doing this for a long time.
4:52 I’m very good at it.
4:53 That only means your chances
4:54 of failure increase with each outing.
4:57 Statistically speaking.
4:59 The odds will be what the odds will be.
5:01 Get out.
5:03 You’re dead, mystery man.
5:05 You’re dead.
