"BLAH BLAH BLAH *STOMP STOMP STOMP* BLAH BLAH YAAAAAAAAAAAAAAAAAHHH GYYYYYYYYYYYAAAAAAAAAAAAAAHHH *Insert Japanese here"
Should I:
a) Open the backdoor and watch (I did this two years ago and they shut the fuck up for almost a year!)
b) Open the window and scream at them to shut the fuck up
c) Open the backdoor and take video footage with my cell phone
d) Politely ask them to keep it down
e) Tell them I'm going to call the cops
f) Do nothing and just post about it more on an internet message board
?
FAKE STEALTH EDIT: They already stopped.

It's this older couple, and they sound so fucking hilarious when they are screaming at each other. Especially when you hear "GYAAAAAAAAAAAAAAAAAAAH" and someone running across the wooden floor. Sounds like a samurai duel or something. I usually just scream "KYAAAAAH" or the same "GYAAAHH" as loud as I can and they shut up, likely out of embarassment.
