Nice thread had a some good laughs, myself being in my 30's some of the things I've done at some point but doesn't seem gross to me. Mind you I've two boys and changed many a diaper so go figure.
As pretty much all my family lives on the west coast (BC) I do know at one point in life growing up my cousins and I had a fish guts fight. Me being the youngest and smallest, I lost big time. Mom said I stunk to high heaven we were all chased back into the ocean to clean off. My cousins made me eat all sorts of things on those fishing trips. But in time you tend to forget.
Fish tank wise ... I slept with a dead goldfish for almost a week. My very first tank, when the last goldfish dissappeared from my tank .... we found him in my sheets when we were changing my bedding. I was 8 or 9 yrs old.
Now one thing I haven't done (knock on wood) so far in aquaria ... taken in a mouthful of tank water. I grew up on a farm and have had to empty a number of fuel tanks .... after that taste, you learn different tricks
