Conversation between Dad and Daughter...

Natalie: "Dad, how does the "S" word thing work?"
Nick (as he begins to panic... what "s" word is she talking about and how am I going to explain it): "What do you mean?"
Natalie: "How does it work? Do you suck the bums?"
Nick (now in a true panic wondering what his innocent 6 year old daughter has been exposed to): "What is the "S" word?"
Natalie: "SMOKE."
Nick (in a huge sigh of relief): "Oh you mean cigarette butts!"
