OK, you can't make a sandwich because all of your bread is stale, so you've decided to make a nice lobster (often called "the sandwich of the sea") instead. There are so many ways to cook a lobster, but because you're still furious that the universe robbed you of your bread, you need to take your anger out on something. You've been told your whole life that lobsters scream when you boil them, so that's what you'll do. You need to boil a small sea creature alive just to hear it scream. That's you. (In this hypothetical, you are a sociopath.)
Be honest. Half of you are cackling right now.
Except it isn't screaming. That sound you hear is actually steam escaping the lobster's shell. When you toss a lobster into a pot of boiling water, steam builds up in the recesses of its shell and it has nowhere to go but out, much like a tea kettle. A delicious, expensive tea kettle.
Not only is it not screaming, your lobster isn't even all that pissed off at you, because its nervous system isn't very complex, so it's feeling little to no pain. So now you can't get a sandwich AND you can't even satisfy yourself with the tortured screams of a defenseless creature. What a sad day for you (you lunatic).
