Two of my favorite TV stars help New Era present their new ‘The Trash Talking Begins’ commercial. ‘30rock’s’ Alec Baldwin is a die-hard Yankees fan while ‘The Offices’ John Krasinski pledges his allegiance to Red Sox Nation. The commercial sees them throwing down the gauntlet for their respective side as New Era asks whos your team? Encouraging fans to side with team Baldwin or team Krasinski via their facebook page. Check it out.
