Thinking Tucker needs to stand up for himself with his boss Mary Hart, Ben films Mary berating Tucker to show how badly he's being treated. But when Emma accidentally uploads the video online, Mary and Tucker become a viral sensation, leaving Tucker in an even worse spot. And Riley asks Danny to stand up to Bonnie and tell her she can't always hang out with them, but Bonnie has a trick up her sleeve to outwit Riley.

Baby Daddy follows Ben, a young man in his early 20s living the life of a bachelor in New York City with his buddy, Tucker, and his brother, Danny. Their lives are turned upside down when they come home one day to find a baby girl left on the doorstep by an ex-girlfriend of Ben's. After much deliberation, Ben decides to raise the baby with the help of his friends and his protective and sometimes over-bearing mother, Bonnie, and his close female friend, Riley.
