Can you hear that? It's the sound of the X-Files theme song, stuck in your head forever.

And that's how Fox wants it. On Thursday, the network released a new teaser video featuring Mulder (David Duchovny) and Scully (Gillian Anderson) in action.

It's only 15 seconds long, but hey, we've waited 13 years for new episodes, so we'll take it.

The new episodes premiere Jan. 24 on Fox.
