Though he praised her professionalism and How I Met Your Mother saw its best ratings ever as a result of her appearance, Neil Patrick Harris warns that “stunt” guest stars like Britney Spears may cause the quality of the show to suffer.
Said Harris: “I'm in the minority that our show does not need stunt casting in order to succeed. I worry that if they start `Will and Grace'-ing us too much, that the show will suffer. And we're all really proud of the content of the show. I mean, viewership is not our game. It's the network and the studio's game, you know. It's the promotion department's game. We wish we weren't opposite an awkward reality dancing competition. But we have no say about that. I just am a real fan of our content. I think we have a great show going, and I hope it's not screwed up by the desire for 700,000 more viewers.”
