Well, I've eaten some strange **** before and I will always try something since there is a fairly good chance I might like it-and by not trying something just because is sounds nasty means one will not eat some truly great things. Lutefisk may or may not be one of those treats but I will withold judgement until I actually try some.
Some if the strange stuff (food) I have eaten and actually liked:
Boudin rouge (blood boudin)
Raw Oysters
Haggis
Raw fish
Steak Tartare
Liederkrantz cheese
Stewed Chicken gizzards, smothered liver
Rabbit,Squirrel,Deer,Goat,nutria,
Strange food I have eaten and NOT liked
Seagull (don't ask

)
Possum, Raccoon
By-catch stew (anybody that has dealt with Vietnamese shrimpers knows what this is).
Armadillo (again don't ask but it also involved mescal, a large fire and three drunk Mexican ranch hands at some ranch in south Texas after a long ago dove hunt. Money changed hands

).
So in other words-I'll try just about anything at least once.
