This will either be the most ridiculous, or coolest, crossover episodes in TV history.

On the May 7 installment of Bones, David Boreanaz's Booth will come face-to-face with baby Stewie from Family Guy.

Here's how the unusual meeting will come about:

Brennan asks Booth to father her child. From there, the typically calm federal agent grows consumed by the prospect of procreating. He's also diagnosed with a severe health issue, which sets the stage for a visit from Stewie, who somehow offers advice to the confused character.

Speaking to TV Guide, Boreanaz joked that Stewie "was good during the actual scenes ... but between takes he literally vanished — nowhere to be seen."
