A little girl walks into a pet shop and asks in the sweetest little lisp: "Excuthe me, mithter, do you have wittal 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 sweet voice:
"I don't think my python weally givth a thit."
