Heh

A precious little girl walks into a pet shop and asks, in the sweetest
little lisp, between two missing teeth, "Excuthe me, mithter, do you keep
widdle wabbits?"
As the shopkeeper's heart melts, he gets down on his knees so that he's on
her level and asks, "Do you want a widdle white wabbit, or a thoft and fuwwy
bwack wabbit, or maybe one like that cute widdle bwown wabbit over there?"
She, in turn, blushes, rocks on her heels, puts her hands on her knees,
leans forward and says, in a tiny quiet voice, "I don't think my python
weawy givths a thit."

My first reaction was:

"The little girl is a little boy?"

My second reaction:

"What kind of a parent dresses their boy like a girl?"

My third reaction:

"The kind that have a son who engages in beastiality. That's sick!"

My fourth reaction:

"Oh... It's a clean joke."
