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.

Wow, I'm gonna go for it!

Thinking of Alison Hannigan lesbianing on TV gives me a hard on. She's hotter than the sun.
