Halpern, who co-wrote the pilot, launched his Twitter account in August to document the random and sometimes profane comments that he says come out of his 73-year-old father's mouth. The account currently has more than 1.2 million followers.
A former host of ET on MTV and Rock the Cradle, Devlin, 29, currently recurs on Cougar Town.
