I was staying at a friends 2nd floor apartment the night before a flight, and really needed a wank. I used a tissue to clean up, and cos I was high, felt paranoid about leaving the living room to flush it in the bathroom (it was 2am and we were all up early). So I threw the sinful tissue out of the window, only for it to get snagged in the branch of a tree right outside, in plain view of the apartment. I tried to dislodge it with a broom handle, to no avail. The next morning, I was smoking out the same window, staring at the tissue and hoping it fell out of the tree before my mate and his flat mate woke up. Luckily, a gust of wind freed the tissue and it fell to a bush below, just seconds before a litter picker walked by, looked askance at it, and placed it in his bin.
It was the perfect crime.
