THE Zipline

(While playing Call of Duty: Black Ops on one of the new maps with our cousin Ben, Josh discovers a zipline. The following conversation is about said zipline.)

Josh: Hey, it's a zip line!

Ben: You can use it.

Josh: I know, it says, "Use zipline."

Jordan: "Use the zipline."

Josh: It says "the"? 

Jordan: Yeah, it does.

Josh: Oh yeah, it does.
