Got a similar story, only involving shog dit. My dad would leave early hours for work and there was always a big pile of it left on the pavement not far from the end of their path. So, for the next week we rig a camera up in the window to see if we could catch the 'culprit'
So, after reviewing the footage for the first 3 nights we see the same thing each night, fat bird from the next street wobbles to the corner, with fat pooch in tow, lights a ciggie, smokes the ciggie, while the dog dumps, then flicks her ciggie and strolls off.
Old man, absolutely 'kin livid, sits and waits for her, goes out after they've paid their nightly visit, shovels it up and follows fatty and friend back to her house, shovel in hand, waits for the door to close and proceeds to shove it through the letterbox then knocks on the door.
As fatty gets near the door she obviously spots the mess and starts screaming and shouting as she opens the door and smears it across her floor. She's raging, proper flipping and ranting like a loon. Dad just stands there, calm as f..., waits for her to calm down and says 'hiya love, you leave one of them outside my house every night, that on your floor is tonight's that you just left, and more often than not somebody will stand in it and walk it onto our floors. So, every time you leave one of them outside our house while you have your ciggie, I'll bring it round and post it for you, anyway I'm off to work now, bye love.
Strolls home, cool as a cool thing in cool town
