A family feud is coming to Thursday nights!

While Tim Daly stars on Private Practice, his son has just signed on for a recurring role on The Office.

Sam Daly debut on the December 10 episode of the NBC sitcom. He'll appear as Oscar’s new, younger boyfriend.

“He looks like Tim, except he has blonde hair,” said Oscar Martinez (Oscar) “He’s six foot tall and really nice.”

While nothing has been confirmed yet, Daly will likely appear on multiple episodes.

Martinez told TV Guide Magazine that it may take awhile before Oscar’s co-workers discover he's gone all cougar on them.

“I’m not sure if people at the office are going to find out about this right away," he said.
