Sometime Lindsay Lohan lady friend Courtenay Semel is the daughter of former Yahoo chief Terry Semel. She is also, as some have described her, a vicious fame-seeking lass. So it makes sense she's being sued by security guard Jaroslaw Jarczok, of Las Vegas' Pure nightclub, who alleges she punched him in the face while drunk, and screamed, "Do you even know who I am, fucking idiot?…Google me, you dumb fuck." Heh. She didn't even demand he "Yahoo" her.
