Carrie Underwood is making her first sitcom appearance tonight on 'How I Met Your Mother" at 7pm on CBS.
She wasn't as nervous as you'd think. She says, "They knew my limited acting experience so I don't think anybody was holding out these high expectations for me. If anything I think they were pleasantly surprised, so they probably had pretty low expectations of me when I walked in."
She'll be playing Ted's love interest so your keyword is "TED" for 250 points.
