A great actress known for beautiful red hair, a smoking body, and playing a lesbian in Buffy the Vampire Slayer, shattering the hearts of thousands of fanboys who continue to live with their parents. Almost destroyed career in Date Movie, now in How I Met Your Mother, not committing any more crimes against humanity.
Dude, that lady walking by you is an Alison Hannigan in terms of hotness.
