This Troper's aunt gladly recalls the time a Job Corps staff tossed a Tandy (a $9000 machine!) out a window in frustration, and ended up trying in vain to fix it.

Ask anyone on the ''{{Achaea}}'' forums what happened to Cain's laptop. (Apparently he beat it up first.)

This Troper's ex girlfriend destroyed a picture of another woman (with whom the troper had never had a sexual relationship, and had last seen her years ago) while taking her belongings from his flat. No biggie, but the narrative dropped the anvil never to trust your flat to a ClingyJealousGirl.

This wouldn't count as defenestration, but when I was in Year 5, rumours were spreading round that a particularly mean teacher had thrown a dictionary at a student's head and then started yelling at him! Luckily, it missed.

A teacher at this troper's schools regularly throws things through the window, granted, it faces a garden and we're in the first floor, and most of the time it's justified since the object that is normaly flinged is the cause, but becomes hilarious when an I-phone was thrwon out and several classmates asked to go to the bathroom simultaneously.

When this troper was in high school, he heard a story about a classmate in an AP Calculus class: the student was playing games on his graphing calculator, when all of a sudden the teacher grabbed it, erased the memory, and handed it back. When the student started going through it to see if any of his games had been spared, the teacher said to put the calculator away "before it turns into Super Calculator and flies out the window".

''Frostsabre.'' Zigzagged to the point that that was added to my list of ArcWords. There was ''always'' someone in my A.P. Euro class that this troper's classmate wishes to defenestrate but couldn't since the windows were too small and opened inward. Even I didn't know defenestration deserved its own TVTropes page.
