With only three episodes left on Grey's Anatomy Season 8, and so much drama on the horizon, we sometimes forget about the medical cases of the week. But the guest stars on the penultimate episode (Season 8, Episode 23: "Migration" ) are definitely something to look forward to.

TVLine reports that Mary Lynn Rajskub and Patrick Fischler “will play a couple in the midst of their third honeymoon when they come to Seattle Grace complaining of mysterious symptoms.” We loved Mary Lynn on 24, when she played Jack Bauer’s (Kiefer Sutherland) suspicious right-hand gal. As for our fondest memory of Patrick, we’re torn between his arc as comedian with a heart of gold Jimmy Barrett on Mad Men, and his role as Phil the anxious Dharma employee on Lost .

Hopefully this on-screen couple’s romantic issues will complement some of the romantic issues of our favorite Grey’s couples during the episode. We love when the tumultuous medical cases involving couples in love inspire our docs to hold each other a little closer.

Catch a new episode of Grey’s Anatomy on Thursday, May 3 at 9 p.m. ET/PT on ABC.
