It's Always Sunny in Philadelphia's Glenn Howerton joins The Fred Minnick Show and discusses the Gang's new project--Four Walls Whiskey. One of which is a blend of American and Irish whiskeys, and the other, which Fred tastes on the show, is a 15-year Irish Whiskey at cask strength. In addition, they discuss what it's been like for It's Always Sunny in Philadelphia to be the longest running live-action sitcom. Fred recalls an episode in which the Gang kidnaps a restaurant critic. Could the same happen to a whiskey critic?
