Best Way to Kill Lobsters

There's a lobster killing scene in "Julie & Julia" that debates the merits of killing lobsters either through boiling in water or stabbing with knives:





and in case the link breaks:

FYI, the song in the background of the scene is the Talking Heads' "Psycho Killer" where the actors replace the word "psycho" w/ "lobster" 

There's also a lobster killing scene in "Annie Hall" where Woody Allen is as inept in killing lobsters as Amy Adams is: 

In case you wondered how Julia Child killed her lobster on her "The French Chef" show, she chose to boil them to death:

However, if you try to boil lobsters in water vs kill them with a knife, you could end up with the negative repercussions faced by the "The Muppet Show" Swedish chef

I guess to be fair, and to engage in plausible deniability wrt lobstercide, you could give knives to the lobsters, let them fight it out, and then eat the loser.
