The Mayans knew what was coming.

Some say Friday, Dec. 21 is the end of the world.

But we feel fine. So, stay up late playing Wii U, because you might not have work, or a world, to wake up to tomorrow morning. Go ahead and blow all of your cash while you're at it. Might as well, right?

And as many theorists as there are predicting doom, they're not all on the same page about how or why.

CONTEST: So, we want to hear it from you. How is the world going to end tomorrow? Give us your predictions in the comments below for a chance to win $25 to Texas de Brazil at City Creek Center.

If you're wrong, we'll pick one lucky winner on Friday at noon.
