Funny story of the day: I got this eye infection and went to the doctor. So I go and say "Well Dr., my nurse friend thought I might have Irisitis or something similar, do you think that's what it is?" He blankly looked at me and said "I've never heard of that, can't figure what that might be." Very reassuring. The examination finished, he sat down and said, "actually I don't know 'tall what you've got, I'll give you two prescriptions."
