A Comedy Trope. There are few visual images that better convey a character's explosive anger with an alarm clock, videogame, phone call or TV set than said character hurling said object through a closed window. Crash! Said action is most always viewed from the outside, only indirectly showing the violent pitch or punt that launches the object. It's funnier that way, especially if the appliance is illogically heavy. (See Offscreen Crash.) While it usually applies to household appliances, other objects can also be featured, as long as someone is propelling them through the window.
