How Was Britney Spears' 'How I Met Your Mother' Cameo?

We told you earlier in the week that Britney Spears was returning to prime time in an episode of "How I Met Your Mother," playing a sweet and slightly nerdy office worker. So how did it go? Did Britney have any meltdowns? Did she run over anyone's foot and drive off?! Well, one of the show's stars, Josh Radnor, who plays Britney's love interest, stopped by CBS' "The Early Show" to set the record straight. (You can check out her performance for yourself when the episode airs March 24.)
