If killing dogfish is a sin, I am toast. I will save you from ALL the gory descriptions of torture, experiments and general biocide (is that a word?)
I can tell you that like the movie "Jaws" they blow up good! And if you think you are good at making herring spin... try adding; flip, barrel roll, shake, flop, stall, tow and play dead...

Okay, I am not proud of my teenage years for many reasons and I am willing mend my ways but I may need help. Is there a dogfish anti-violence support group? DADF? Dogfish Against Drunken Fishermen? DBA? Dogfish Beaters Anonymous?
I can't imaging eating them though, Mercury or not. Mom taught me to never play with with my food. Therefore, I could never see them as tablefare.

Is it still okay to play with them though? Have ya ever grabbed em by the nose, turned them upside-down and let them chew on stuff? Pencils, bait, paper or whatever is laying around. They are pretty good at crushing Coke cans. And the spikes... have you ever made them stab stuff? Now that is fun!

Let me know...
