Marc Maron's WTF podcast now clocks in at 585 episodes. Certainly one I remember -- and so does Maron too -- is Episode 400, which featured the godfather of punk, Iggy Pop. Above, an animated Marc Maron recalls the many musicians he's interviewed in his Los Angeles garage. And especially the summer day when Pop paid a visit, tore off his shirt, and gave his own nipple a little twist. Good times in LA.
