Since we're on the topic of people who never should have been given a microphone, you kids should know about Wing.
Who is Wing? Well, aside from being a woman who clearly has far too much spare time on her hands, she's a Hong Kong native who immigrated to New Zealand about 10 years ago and started taking singing lessons as a hobby.
For a while, her "career" was limited to gigs at local nursing homes and hospitals. But then those crazy boys at South Park discovered her and wrote an entire episode around her covers of Abba songs.
Almost overnight, Wing became an international cult sensation.
While her tone-deaf and rhythmless deliveries of Abba standards are enough to make your ears bleed, her covers of AC/DC heavy metal hits -- including "Back in Black" and "For Those about to Rock" -- are nothing short of apocalyptic.
Don't believe me? Then check out these videos of Wing singing some of her most gut-wrenching karaoke tunes during a performance at a university in New Zealand.
"I Want to Hold Your Hand"
"In the Ghetto"
"Over the Rainbow"
"Close to You"
