" ARTHUR: How do we get out once we've made the plant?
(to Cobb)
I hope you've got something a little more elegant than shooting me in the head like last time.
Arthur tilts back in his chair. Yusuf turns to Cobb.
COBB: A kick.
ARIADNE: What's a kick?
Eames slips his foot under Arthur's chair leg. TIPS it- Arthur's legs SHOOT UP INSTINCTIVELY for balance-
EAMES: That, Ariadne, would be a kick.
COBB: That feeling of falling which snaps you awake. We use that to jolt ourselves awake once we're done. "
