Born March 24, 1974, best known as Willow Rosenberg on Buffy the Vampire Slayer and Lily Aldrin on How I Met Your Mother.

She had small roles in films like My Stepmother is an Alien (as the daughter) and Dead Man on Campus before her breakout film role as Michelle Flaherty in American Pie, where she shocked everyone with the line "This one time, at band camp, I stuck a flute in my pussy." The world was never the same after that moment. It's always the quiet ones.

Married to her former Buffy co-star Alexis Denisof, and a mother, as well as starring on the hit sitcom How I Met Your Mother as Lily. Her daughter seems to have taken up her mother's banner of truly ridiculous levels of cute.

She has even been immortalized in the song "Alyson Hannigan" by the Klopecs:

 I first saw you when I was ten,

Your stepmother was an alien.

You were attacked by an alien bag.

Dan Aykroyd he was your dad.

 One day I turned my TV on

I saw you dancing at the Bronze

Where all the kids just wanna dance.

Oh Willow, I wanna be your man.

 Oh Alyson, Alyson Hannigan

I can't wait until the day I see you again.

A, A, Lyson.

This actress contains examples of:

 Willow: You're supposed to stop me when I do that.

Oz: I like it when you do that.

 Joss Whedon: "There is nothing more painful in the world than Aly when she makes her big eyes. She makes her big, hurt eyes, there's nothing you can do. She just kills you."

 Thugboy: "This Alyson Hannigan is a menace."
