The Meg quotes
Dr. Minway Zhang: We have a shark cage and spearguns on board. If we can shoot the meg in a soft spot like its mouth or gills, we can inject it with something lethal.
Mac: Whoa, whoa, whoa. It's gonna take at least 20 minutes to rig the cage. And that thing will be gone in two.
Jack Morris: Why don't you just put a tracker on it? Don't you guys ever watch Shark Week? You have one of those, like, GPS tracker tag thingamajigs. Keep an eye on the shark till the cage is ready.
The Wall: We should be able to put a tracking dart in that dorsal fin.
Jack Morris: You're welcome.
