I threw a figure 8 puffer out the window of Centennial Hall at Truman and into the ventilation fan below my window several years ago.
That little bastard was wrecking everything he could get near and I'd had enough of that. So I netted him and chucked him out the window. He one-hopped off the laundry facility roof and into the fan.
It was in more early, far more impetuous days of owning a fish tank; my original 42 gal hex (which I still want to set up as a seahorse tank one of these days; perfect shape for it).
Not one of my better moments.
It's my own fault for expecting the Titanic to beat the iceberg this year.
