Bands making appearances in cartoons is tradition, from The Smashing Pumpkins and Sonic Youth rocking Homerpalooza on The Simpsons to a cameo from Radiohead on a particularly demented episode of South Park (yes, they make fun of a kid for being tricked into eating his parents).  Later this month, American Dad will continue the lineage of real-life rockers lending their voices to animated versions of themselves when one character becomes obsessed with Louisville, Kentucky’s My Morning Jacket.  The episode, titled “My Morning Straightjacket,” also features a cameo from Zach Galifianakis and is slated to air on November 22 on FOX.
