Sarah Michelle Gellar (Buffy) has done a lot of voice actor work in adult animated shows, especially as girlfriends that have effected the boys of the family.
King of the Hill
"And They Call It Bobby Love" aired in 1998, of the third season of "King of the Hill." Marie was a vegan older girl that Bobby kissed and broke his heart. This aired during the height of Buffy popularity. I think this was a good episode.
Simpsons
She played Gina in 'The Wandering Juvie" and recently reprise the role. She played a girl that Bart falls for in Juvie. It wasn't a good episode. This aired in 2004, after Buffy.
American Dad
"Virtual In-Stanity" aired in 2011. She played an avatar that was really Stan, in order for his son Steve to have a girlfriend.
In American Dad, Alyson Hannigan (Willow) also co-starred in the ep as the ignored Chelsea.

In 2004, she played a character obsessed with Bobby in "Talking Shop."
The Simpsons
