Howard's Ever-Expanding Media tour

Howard also planned to do Piers Morgan, Jimmy Fallon--and maybe Jimmy Kimmel, as he and Beth are considering at trip to LA: "I might even do Conan."

Howard said he'd do most of the late-night shows, but had to draw the line somewhere: "A lot of them are girl shows. Like you know, heavy older female audiences. And I'm like, why the f--they're not going to buy the Sirius app. They don't even know what an app is."
