New Era has had some cleaver advertising campaigns around baseball and baseball rivalries. The intense rivalries depicted by New Era began with Alec Baldwin and John Krasinski as the Red Sox took on the Yankees.

New Era is at it again but this time we head to the Windy City of Chicago as the Cubs face-off against the White Sox. 

Nick Offerman, who plays Ron Swanson from "Parks and Recreation" is defending the Cubs and the traditions bestod upon one of the oldest baseball franchises. While Craig Robinson, better known as Darryl Philbin from "The Office" fights for the White Sox.

It's all fun and games until Robinson takes it a bit too far with his jab at the pizza from the North Side of Chicago.
