    Good Lord! if I renamed myself Cathy Cleavage could I sucker you people into doing my homework for me, too? Are you THAT easy?

    I agree with Nate. Don't hand over the answers until some effort has been shown.:approve:

    I agree 100 percent dont... i mean if you spent the same amount of time typing those questions on google you would get the answer.

    cmon guys have some common sense. this is some guy with the screen name "bobbies" and everyone is standing in line to handover the answers.
