When they're not busy switching actresses, Lauren Anne "Laurie" Forman is Eric's sister on That 70's Show. Laurie is definitely a manipulative *itch and a bit of a slut. We love her just the same.
Eric: Didn't you just, like, flunk out of college?
Laurie: Get bent, twerp.
Eric: Wear a bra!
(Laurie comes to the basement to do laundry, wearing only a long t-shirt)
Laurie...I want you to stay off my case, it will only take me a minute.
Eric: I don't think Kelso's gonna last that long.
Laurie: Too bad. It's not like I'm completely naked under this. I'm wearning underwear. (she lifts her shirt) See? If we were at the beach you wouldn't even notice me.
Hyde: If we were at the beach, Kelso would be in the water right now.
