Leave a few wrecked cars and some shopping trolleys (plus and old fridge) in the front garden.

Have a nice loud recording of someone practicing on a drum kit and blame it on the neighbours kids.

Buy some fresh durian, a tasty fruit that when opened smells like a sewer, and leave it in the kitchen, or get some well fermented kimchi, a rather delicious but smelly pickle made of fermented white cabbage, garlic and chillies, and leave that in the kitchen too.

A Chiniese alternative would be fermented dofu (tofu) which when fried in oil smell a lot like horse pee.

Come to think of it then invite the viewers to stay for dinner!
