This is no joke, I had a pathalogical fear of pickled onions when I was a lad!!!!!
I'm over it now though.
Also I remember a time when I was about 7 or 8 and my older brother told me that if you ring your own telephone number the devil will answer. I proper fell for it but eventually plucked up the courage to ring it. There was a short pause, then a crackle, then a dial tone then a ring tone....my heart was in my mouth....then to my horror a bloke answered!! I Dropped the phone and flew upstairs and hid under my bedsheets in tears thinking the devil was after me now!!! Now that was fear!
