A Moth walks in to a dentist's surgery, sits in the chair and proceeds to open his heart to the dentist.......
Moth: I was abused as a caterpillar.....my parents deserted me......I have nightmares about being eaten by spiders......I'm ugly with no self esteem.....I've got no friends and sometimes feel suicidal etc etc.
The dentist turns to the moth and said 'Man, you're really screwed up aren't you.........I think you should really see a Psychologist. Why did you come to see me?'
The moth said 'Well..........the light was on'.
