Grant Show is trading in a polyester suit for some circa-2008 scrubs.

The Swingtown stud has signed on to appear in an early Season 2 episode of Private Practice, Entertainment Weekly reports.

This guest star news comes the same week as Billy Dee Williams has agreed to appear on the Grey's Anatomy spin-off.

Grant Show's character, a charming and flirtatious doctor, has ties to a Private Practice regular. Hmm. Who could it be?

Very interesting, regardless. Any thoughts as to which Oceanside staffer may have a skeleton in his or her closet?
