His appearance on the RAW 9/17/12 episode in a segment where Jared from Subway is giving out sandwiches to WWE superstars. Ryback shows up (Jared predictably gives a bit of an Oh, Crap expression as the camera pans to bring him into view) and shouts, of course, "FEED! ME! MORE!" so Jared gives him a footlong sub. Ryback contemplates it for a second, and then yanks a second footlong sub from the table as he walks away. This is especially funny if you know that, in and out-of-character, Ryback is a notorious Big Eater, so more than likely those two sandwiches (if not more) were probably consumed at some point shortly thereafter.
In his Skip Sheffield persona, his So Bad, It's Good catchphrase: "Yup yup yup, what it do!"
Shouting "I DIDN'T TOUCH YOU, STUPID!" after using Santino Marella as a weapon against Mark Henry, who had already gotten around their no-contact clause to attack Ryback by pushing a barbell down on his throat. Also, taking the time to ask Santino if he was okay before hoisting him over his head and chucking him at Henry.
