Just when you thought you'd never have to hear 'Achy Breaky Heart' again -- except for when someone mentions that it was the only hit song that Miley Cyrus' dad had back in the day -- it's returned like an unwanted friend from college who wants to know if you got his messages.

Well, it's sorta returned. And like most movie and music sequels, 'Achy Breaky 2' is even more terrible the second time around.

With a cameo by 127-year-old talk-show host Larry King, space aliens wearing Barbarella's castoffs and special effects from a 1985 MTV video, 'Achy Breaky 2' is all kinds of bad. It makes Miley's 'Wrecking Ball' video look like 'Thriller.'

Oh, and then there's rapper Buck 22, whom we've never heard of and who's now probably lost whatever little cred he had. (Actually, he's Dionne Warwick's son, which means he was related to Whitney Houston . . . if that explains anything about his ambitions.)

Plus, there's twerking -- which must run in the Cyrus family. Thankfully, it's the sexy space aliens shaking their barely clothed behinds, not the skeevy-looking Billy Ray Cyrus, who pretty much just stands there with his guitar and tats trying to look badass. Buck 22 does most of the steering, since 'Achy Breaky 2' is his song. But everyone's gonna blame Billy Ray for it.

You can watch the entire mess above. Warning: It may be the longest three and a half minutes of your day.
