Halloween and The Challenge are two things you may not put in the same sentence -- but through the years, several incidents on the adrenaline reality program have resembled traditions and topics associated with All Hallows' Eve. And no, we don't mean a rousing rendition of "Monster Mash" with the contestants and host TJ Lavin (but that would be highly entertaining, no doubt).

In honor of the holiday, relive some frightening and disguise-filled incidents from the MTV staple -- and share your fave Halloween-themed moments from the series in the comments!
