The Mullets are blue-collar, wrestling-loving, light-hearted, optimistic brothers who don the hairstyle that bears their surname ("business in the front, party in the back"). The 20-something brothers, who sport identical mullet haircuts, are actually a study in contrast. Dwayne Mullet has a loud, in-your-face demeanor, while Denny Mullet is a quieter, more thoughtful, easygoing guy. Their mother Mandi Mullet-Heidecker, a warm maternal type who couldn't be more proud of her offspring, no matter what they do, recently married Roger Heidecker, a clean-cut game show host who is the polar opposite of her boys and her former life. The siblings live life to the fullest while dreaming of bigger and better futures, though their fantasies are out of step with their reality.
