I think every sitcom in the history of television (since the advent of the answering machine) has done that episode where someone leaves an awful message on someone else's machine/voicemail. The one that stands out in my mind is the episode of "Seinfeld" where George leaves message after message - each progressively more angry and belligerent - for a date who seems to be avoiding him after they shared a good time together. Turns out she was out of town for the weekend, forcing George and Jerry orchestrate this elaborate plot ("Tippy toes! Tippy toes!") to steal her answering machine cassette!
So why do sitcom writers tap into this scenario again and again? Because when it happens to someone else, it's hilarious.
When it happens to you? Not so much, ESPECIALLY if that embarrassing/horrible/*gulp* angry message is for your boss, a client, or a co-worker.
