Details have emerged about a much-anticipated Tony DiNozzo "origin" episode of NCIS. On May 3, the show will take us back 10 years to his days with the Baltimore P.D.

According to Entertainment Weekly, Scott Grimes (ER) will play Det. Danny Price, a former partner of Tony who worked together with DiNozzo as cops in that city.

It's unclear if Grimes, who already announced his gig on Twitter, will appear in the present as well as in flashbacks, or just one of the two. But it should be fun to watch.

In November, NCIS flashed back 20 years to reveal what happened in Amsterdam to shape Leon Vance (Rocky Carroll), and what led him to become the director of the agency.

In preparation, Carroll and guest star Michael Nouri, who plays Ziva's father Eli David, spent a ton of time in the makeup trailer to shave the years off, with convincing results.

Will Weatherly undergo the same transformation? Can he shed 20 pounds in the span of a week? What do you think this Tony episode will tell us about the resident cutup?
