Sometimes you want to go where every pun will cause you pain — so grab your wallet, stoke your thirst, and join J. and Collision in Spider Robinson’s Callahan’s Crosstime Saloon, where every man gets his chance to be heard, every pun gets its chance to get aired, and several women step up to help a man laugh, love, live, and learn just a little bit about himself and his feelings. Come to Callahan’s for the booze, but stay for what some listeners are calling the greatest musical segment in podcast history.
