John Oliver is not a bad thought. His comedy is a bit forced sometimes, a bit like Stewart can be, but still funny. I like all three of them really, Stewart, Colbert, and Oliver but Colbert is the most natural.
Oliver's HBO show is premiering at the end of this month.
I dunno. I guess if this is what Stephen wanted, we'll have to trust his judgment as an entertainer. But the typical late night format doesn't interest me very much.
