Well, they've invaded just about everywhere else so it was a matter of time, really.
On last night's episode of CBS' The Late, Late Show, host Craig Ferguson opened with a surprisingly fanboyish introduction of the classic Doctor Who menace The Daleks to mainstream America.
Ferguson reminisced about watching the Daleks on Doctor Who as a wee lad, discussing their various features and the now-thankfully-obsolete stairs weakness, and was even prone to hugging it as if he was former Doctor Who companion actress Katy Manning. (You non-Whovians out there can Google that reference for yourselves, although be aware it's Not Safe For Work.)
Tonight's episode of The Late, Late Show with Craig Ferguson should be even more promising, with the scheduled appearance of none other than the Eleventh Doctor, Matt Smith. Just think, a current Doctor appearing on a mainstream U.S. late-night talk show...Madness. Absolute madness.
