In this scene, Big Mike describes his Subway sandwich and sauce of choice by name while holding it up into frame. I am still waiting for Jared to show up or for a subplot to arise in which Big Mike decides to lose weight by taking the Subway challenge.
A better promotion for Subway would be to take a cue from The Last Starfighter, and have people inducted into the CIA from random walk-ins to Subway locations. Your taste buds can handle prolonged exposure to relatively bland flavors and your bowels can withstand the awesome power of the meatball sandwich, somehow this makes you a perfect candidate. Forget your old life and come with us.
