How to annoy construction workers?

-These people in the flat above me are really loud with their construction. anyone have any creative ways to get petty revenge? i know its not their fault and that they are doing their job but im open to anyways to get petty revenge on the people who own the place as well. thx! also try to make it legal lolWell, they are doing their work, if you have any problem then call building secretary they might help you n there. If you are doing job at your office and someone will annoy you , how you going to feel about it. They are only construction worker who are supposed to work hard every day for a single meal.
Throw a grenade and run.
Throw marshmellows at them, its legal AND FUN :) Plus they can nomnom them. You could also write something on them with a sharpie. "Shut up." "You free tomorrow night?", etc. Have fun. :)
Why not just let them do their job?
Serve them juice or better yet, join them.
