10 Weirdest TV Show Crossovers

10. Sleepy Hollow/Bones

Bones: The Resurrection of the Remains

Sleepy Hollow: Dead Men Tell No Tales

This two-part crossover special joins the worlds of Bones and Sleepy Hollow. Sleepy Hollow takes place in a supernatural world where Ichabod Crane awakes in 2013 and befriends a cop. Like Sleepy Hollow, Bones is a mystery, but unlike its fellow Fox show, it uses a real-world setting without any magic.

Consequently, having these two shows exist in a shared universe is a bit of a problem for a series like Bones that relies on "hard facts" and "science" to solve their cases.

That said, this spooky episode starts with Booth and Brennan finding a decapitated body, which brings Crane and Abbie to D.C. to help. Set in the Bones universe, despite dealing with a magical skull that is said to bring people back from the dead, the ep concludes that no magic was involved. Just normal, rational murder.

The second episode takes place in the Sleepy Hollow universe and stomps all over the rules of the Bones episode by being about a zombie army. Brennan and Booth never find out about the supernatural elements though, and it all ends well for everyone.
