I have cooked many lobster and crab in my life. I always steam my lobster and boil my crab. I was told by several people that the lobsters scream when they are put in the pot, but I have not heard any protest to this day. I think I will purchase a lobster soon and give in a warm steam bath and a butter massage. Now I’m drooling like Homer Simpson did when he ate Pinchy.
They don't scream. It's actually the air in the shell escaping as steam. When I first heard that story, I was playing in a band and we put a microphone over the pot when we put one in.
