A straight factor is important in any comedy, because you need something to tee it up and also to ground it.
I think I failed miserably on NewsRadio. I was very nervous because of the caliber of the cast - especially Dave Foley - so I think I did a terrible job.
I have endless playlists on my iPod so will throw on, say, Bruce Springsteen or The Smiths, depending on what kind of day I'm going to have.
