Patrick Walsh has been a terrific sitcom writer on some of the longest running sitcoms of the past decade, including "2 Broke Girls" and "It's Always Sunny in Philadelphia." But he's dreamed of bringing a different style of comedy to TV and he's now getting his chance, as the showrunner of the upcoming CBS sitcom "Biblically Speaking," out Feb 26 and hilariously focused on a man in midlife crisis who decides to live his life literally in accordance with every rule in the Bible for a year. Based on the terrific memoir "The Year of Living Biblically" by AJ Jacobs, this is game-changing stuff for Christian-themed entertainment and it's done extremely well. Walsh sat down to discuss his career and the challenges of getting Catholicism and Christianity right while being very very funny.
