Guests Sarah Silverman, Brad Meltzer, Kasper Hauser. We return to our nerdiest theme. Sarah Silverman is the hottest comedian in the country as her film "Jesus is Magic" hits theaters. Brad Meltzer is a best-selling novelist, and the author of the controversial DC Comics graphic novel "Identity Crisis." The Kasper Hauser Skit Club are San Francisco's favorite sketch comedy group... they perform a sketch and read some of their fake Craigslist postings.

Guests Judith Belushi Pisano and Tanner Colby. John Belushi was one of the great comics of the late 20th century. Belushi Pisano and Colby are the editors of the new book Belushi, an oral history of his life and times. The show also features clips from the National Lampoon Radio Hour which feature Belushi. Oh! And be sure to visit maximumfun.org for a neat web-only bonus mp3.

Guest Tom Scharpling. This week's show is given over to our pal Tom Scharpling, host of the cult radio program "The Best Show on WFMU." We hear two tracks from Tom's new CD with partner-in-joke Jon Wurster, recorded live on The Best Show. The program features comics calling in with assumed personae, being interviewed by the unflappable Scharpling.

A little message with some info on how you can use your status as a Sound of Young America listener to win a copy of the new Onion compilation, a DVD of "Martin & Orloff," or even a DVD set of Arrested Development season two.

Guests Henry Rollins and John Hodgman. Henry Rollins' 25 years on the road with Black Flag and The Rollins Band have left him really, really awesome. Also, John Hodgman, This American Life and McSweeney's contributor, talks about his new book, The Areas of My Expertise, and about hobos.
