I don't recall anymore where I head this story, but it still makes me laugh.
A little child was on a bus with her mother, when a young man stepped into the bus. He was a punk-rocker - his hair was sticking in spikes into every direction, he had made up his eyes with black mascara, had a safety pin through his cheek, a long black coat with chains hanging, and heavy boots.
The little girl looked at him in awe and then whispered to her mother in a loud voice everyone could hear:
"Look Mummy! A goblin!"
Everyone started laughing. Not exactly the effect the young man was looking for... :D
