"Ok lets go" is just way too open to interpretation.

Anyone who's ever let a misinterpreted text end a friendship, job opportunity, or a marriage will relate to this. Key and Peele are on fire this season, and this sketch about how wildly we can misinterpret a text communication pretty much captures why we're all so goddamn angry all the time these days. I mean, when Jeff said getting a drink sounded "real cool" was he serious or was he saying "real cool dickbag"? I'm going with the latter and he's dead to me.
