Bad Boys Rape Our Young Girls But Violet Gives Willingly

As taught in college. In my situation, our professor disappeared mid semester, as he was arrested for child porn, and was the biggest supplier of child porn in Colorado at the time...

RING, RING, RING, RING, RING, RING, RING.... BANANA PHONE!

Or, My personal favorite...
