The Jeffersonian is getting its newest squintern — and its oldest!

Fox announced Thursday that the legendary Betty White will be guest-starring on an episode of Bones this season. White, who's fresh off wrapping the final season of Hot in Cleveland, will play Dr. Beth Mayer, who assists Booth and Brennan's team in (what else) a murder investigation.

"With a half century of work under her belt, Dr. Mayer is without a doubt the world's most experienced forensic anthropologist, which will lead to some serious competition with Dr. Brennan," Fox teased in its press release.

Here's everything we know about the upcoming crossover episode of Bones and Sleepy Hollow

The murder will be somehow related to fantasy football, a topic on which White's character is an expert. (We're keeping our fingers crossed for some NFL hotties to stop by for a cameo.) The episode will air some time in October.

Bones returns Oct. 1 at 8/7c on Fox.
