If you find out where he lives/which flat he lives in, just pour petrol through his letter box, I know if I went out and came back in and petrol was poured through my letter box I'd kack my panties.Don't light it obviously, just had visions of seeing it in a film or something, would be good. Guy sounds like a bit of a 'rick but like OBM said it would be annoying hearing squeeking brakes when you're "chilling"
