VIDEO: Alyson Hannigan on Britney
"How I Met Your Mother" star Alyson Hannigan says they have the best writers in television. Well, you got that right, sunshine! Your comedy is hilarious and so are you, Lilly dearest. Former "Buffy" star talks about Britney, the show's charity website and next week's season finale. Judging by the fact there will be a cliffhanger, I hope season 4 renewal is a shoe-in.
