When Sam and Toby were looking for the Wesley Police Station:
Toby: We’re going the wrong way.
Sam: No, we’re not.
Toby: We’re supposed to be going east.
Sam: We’re going east.
Toby: How do you know we’re going east?
Sam: The sun rises in the east.
Toby: It’s dark outside.
Sam: Also, that bright star in the northern sky is Polaris.
Toby: So what?
Sam: I’m using celestial navigation.
Josh: What’s going on?
Toby: Sam feels we’re zeroing in on it.
Josh: You haven’t found it yet?
Toby: We’ve been navigating by the north star, which turned out to be the Delta Shuttle from LaGuardia. It’s a miracle we’re not in Nantucket right now.
