In what could be one of the strangest cross-promotions FOX has ever tried (ponder the weight of that statement a moment), the night time drama Bones will soon feature an animated character from the ribald comedy Family Guy. That’s right, FOX fans: David Boreanaz and Stewie Griffin will soon share screen time.

Evidently, Boreanaz’s character will suffer hallucination-generating health problems during episodes of Bones which will air in May. He’ll end up in Quahog, Rhode Island, home to the animated Griffin family. “This is going to sound odd,” began executive producer Stephen Nathan, “but it is a completely believable event.”

He’s right…that does sound odd. And extremely, wholly unlikely.

“There’s medical research to back up what’s going on with Booth [Boreanaz’s character]. There are conditions where you can see cartoon characters,” Nathan explained. “It was always conceived to be a realistic hallucination.”

Of course, it doesn’t hurt that Family Guy is very popular. Seth MacFarlane, created of the animated series, will “sign off on all of Stewie’s dialogue. Whatever Seth wants to do is fine.”
