A tired cliché, I realize, but pseudo-celebrities keep pulling out variations of that line when all else fails. Case in point is Courtenay Semel, whose only legitimate claim to fame is purely biological. She's the daughter of former Yahoo CEO Terry Semel. Yipee. Anyway, a security guard at Caesars Palace filed suit against her for beating him up while allegedly intoxicated (suit was filed in L.A. Superior Court – I’m not sure why). From TMZ:

One thing led to another and he eventually handcuffed Semel, the GF of Tila Tequila. That's when she allegedly struck Jarczok in the face and uttered these soon-to-be immortal words, which deserve a separate line in bold type: "Do you even know who I am, f**king idiot?...Google me, you dumb f**k." Jarczok says he's been humiliated and "anxious about receiving harassing comments by friends..." He wants unspecified damages.

Two sides to the story and all that, but if you take her advice and do a Google search you will find all kinds of citations – none of them connected with actually accomplishing anything, other than being a spoiled rich kid.
