just another day at the office
Used in a situation where you haven't done anything cool or unique, and your day was as boring as ever; but it also can be used in awesome situations, like when your buddy Person 1 sees you parachuting off of the 2nd floor. TL;DR: Synonymous with "same shit, different day".
Person 1: So, how was your day? Person 2: Just another day at the office. Sam: Jesus, they worked you over good. You all right? Nathan: Just another day at the office.
