A blond went to the dentist.

“I want you to paint my teeth blue.” – the blond.
“What!?” – exclaimed the dentist.
“Just do it!!” – the blond.

So the dentist painted her teeth blue. The blond went back to her car and called her friend to talk about many things. While she was driving a policeman stopped her.

“Mam, your were talking on your mobile while you were driving. Here is how much you must pay.”

“Oh come on!! Don’t you see I have blue-tooth?!”
