Fiddleheads fail

I confess, I fed us fiddleheads raw in a salad last week, and no I did not think to boil them first, and yes we had a giant bike ride when we noticed that one of these things just doesn't belong here (in the belly). I had some mild discomfort and he had a full two day onslaught. Need I say more? Just google fiddleheads and you will see you should not eat them RAW. whoops. He will not let me forgot that I owe him because I poisoned him- do you know how awful that sounds?!?
