Cigarettes
A friend's 7-year-old daughter is very articulate and intelligent but, like her mum, completely nuts.

One day she sidled up to me while I was standing in the back garden having a fag, and said:

"Why do you smoke?"

"Erm...because I'm addicted to cigarettes. Smoking's very bad for you."

"No it's not."

"Yes it is! It gives you cancer."

"No it doesn't."

"IT IS!"

"Then why do you do it if you know it's bad for you?"

Hmm. Outsmarted by a 7-year-old.
