Cindy Crawford laying out on a yacht topless this weekend in St. Tropez is pretty much why God created the word MILF.  For real.  It's in the bible.  I think it's towards the back.  They were talking about Sarah, I think.  She was smokin hot apparently.  And they said that's why Abraham was all up in that shit.  Actually, I can't lie to you, I just made that up.
