I'm a pretty hardcore arachnophobe, but that's not too weird. Living in Australia with arachnophobia is hardly fair though.
But I have a totally irrational fear of ibis birds. Well, for me it is rational, as they seem to want to attack me whenever I'm in their vicinity. And look at them... they are devil birds.
That and I'm a little 'afraid' of baby corn. I think I'm allergic to it in some way, I'm convinced it gives me migraines. I won't touch anything it's come into contact with. Yes, I'm a little mad.
