I don't think anyone could ever beat one of my D's extended family in Oz. I used to be in hysterics laughing at uncle G's antics of nosiness. He knew the engine sounds of every car in the road and told me one teatime that so-and-so across the road was coming down the hill ( without him looking out ) and, he said " you'll hear a large bang ". Yes, there was the bang, right into the garage doors which were peppered in dents from her arrival. " Throwing out time " apparently 
He was a corker when it came to being nosy, but it used to make me laugh as it was quite an art form. The best was when he stayed up to catch the person with a pooping dog as it was always in his garden. Anyway he spied the culprit---his next door neighbour taking the dogs for a late walk so next morning he shovelled up the mess and threw it over the fence along with more which was around. I often wondered what the neighbour thought getting more poop than the dogs had left.
He was also a " shouter out of the drivers window " man too and one day a car cut right across him. That was that, after a flurry of language Aussie twang, shouting " you stupid b---h, the person turned around and it was a man with long white/blonde hair. I slid down the back of the back seat
couldn't stop laughing. He thought it was a woman.
If ever there was an Elmer Fudd it was him.
