My first flat was this bogging wee number in Dalry. My favourite neighbours were the fucking bum balloons above us, who's bedroom was right above ours. Usually you'll know your neighbours are shagging because you'll hear some kind of rhythmic noise and go "that'll be the bed getting knocked about because their riding" - not the case with these dafties.
The Betty was one of they "noisey customers". But not an "ooo" or "ahhh that's the spot" kind of noisey. For the entire duration of her getting her bacon vault filled in by her man friend, at the top of her voice, she'd make this noise which was identical to the noise Dr Zoidberg makes in Futurama when he skuttles away. A sort of "WOOOOOP-WOOOOO-WOOOOP" noise.
That.
Every night.
For about an hour.
I really should have evened the score up by blowing into a kazoo the whole time I was getting my hole but sadly I didn't think of that at the time.
