The oft-referenced Mr. and Mrs. Kerkovich will make their debut in the ABC comedy's upcoming third season.

More parents will pay a visit to the Happy Endings crew in the series' third season.

Following parental appearances from Megan Mullally, Damon Wayans and Michael McKean, the ABC comedy has added two guest stars to play mom and dad to siblings Alex (Elisha Cuthbert) and Jane (Eliza Coupe). An ABC rep confirms to The Hollywood Reporter that Harry's Law actor Christopher McDonald and Airplane! star Julie Hagerty will take on the previously unseen couple, as first reported by TV Guide.

The duo will appear in the sixth episode of the upcoming run, when Alex and Jane are tasked with throwing a birthday party for their hard-to-please father. Jane takes it upon herself to think of Serbian-themed jokes for the festivities.

McDonald, who has recurred on Boardwalk Empire, comes to Happy Endings from a starring role on NBC's now-canceled Harry's Law. Hagerty, the famously flighty flight attendant from Airplane!, has been on Malcolm in the Middle and CSI.

Hagerty is repped by Innovative Artists, and McDonald is repped by the Gersh Agency.
