These viral videos are actually ads for New Era Cap Company, which is the exclusive manufacturer and marketer of caps for all U.S. major league baseball teams, minor affiliates and more than 200 U.S. colleges and universities. The videos don’t mention headwear until the close, but viewers recognize the rivalry, antics, jabs and banter of sport fanatics just by seeing the logo on the caps. The Chicago Cubs and White Sox caps make clear each wearer’s team loyalties and “tribal ” identifications.

Starring popular character actors Craig Robinson and Nick Offerman, the series of video ads are hilarious – and probably very close to reality. The ads follow on the heels of another Brooklyn Brothers ad series for New Era, starring actors Alec Baldwin and John Krasinski and the rivalry between the Yankees and Red Sox.
