Generally, the talk is non-political and skews to adult tastes. The gang loves to stomp the borderline of naughtiness without crossing over into outrage and the witless. The double entendres are often little miracles of comic invention, sounding dirty, but delightfully harmless.
The Bob and Tom Show is heard on 150 stations coast-to-coast, but only a few free stream the broadcasts online. I listen mornings via WOFX-FM, Cincinnati (5-11 ET) and KHKK-FM, Modesto (5-9 PT), plus WIOT-FM, Toledo (5-10 ET) and KKGL-FM, Boise (6-10 PT). Check Bob and Tom's Affiliates page to locate others.
If you're open to a pay subscription, Bob and Tom's VIP package is reasonable, packed with tons of content. The centerpiece is the commercial-free broadcasts on demand whenever. An archive of complete programs are accessible to enjoy via computer or podcasts. Thousands of best-of bits are also catalogued. See their Oddities pages for no-charge audio highlights, text humor, and funny pictures.
