A little girl walks into a pet shop and asks in the sweetest little lisp, "Excuthe me, mithter, do you keep wittle wabbits?"
The shopkeeper gets down on his knees, so that he's on her level, and asks, "Do you want a wittle white wabby or a soft and fuwwy black wabby or maybe one like that cute wittle brown wabby over there?"
She in turn puts her hands on her knees, leans forward, and says in a quiet voice, "I don't fink my pyfon weally gives a thit!"
