Have you been hearing about the problem of Dying Lobsters? There are many ways to do this. One of the easiest is to put the lobster into a freezer and kill it that way. Alternatively, you can use a sharp chef's knife and quickly stab it through the body. Be sure to use a ribbed sheet pan to catch any spilled liquid. You can also use a sharp knife to cut right under the eye of the lobster to create a cross.
