America runs on Dunkin’ and apparently so do the Afflecks! Ben Affleck and his “cousin” The Secret Lives of Mormon Wives star Jen Affleck steal the spotlight in a new Dunkin’ commercial, where Ben’s iced coffee obsession takes center stage, and Jen hilariously plays the voice of reason. Fans say the spot is the perfect blend: a little sweet, a little sassy, and totally caffeinated.

Spoiler: They are not really cousins!
