help me out guyz.

the neighbours this year are THE biggest set of cunts in the world. it seems their sole intention is to prevent me from having any sleep. for the last 3 months they've spend 4 nights a week staying up until the early hours of the morning listening to shite music stupidly loud, then getting up a couple of hours later and either watching tv or playing gears of war at a ridiculous volume.

example, last night, kept me up til 5am, then all got up at 9am and started playing video games, and i was woken up by machine guns that literally sound like they were in my room.

we've written letters to the letting agent and the council, but it's still going, so i want to take things into my own hands.

suggestions for horrific things i could do to them/their house? (without it being too obvious it was me, don't want to lose my deposit, see.)

thnx
