Actor Tim Allen is reuniting with his former onscreen son Jonathan Taylor Thomas for an upcoming episode of his hit U.S. show Last Man Standing.

The 31 year old played Allen's middle child Randy in long-running American sitcom Home Improvement, and now they're teaming up for the first time in over two decades on the veteran's new comedy.

Taylor Thomas will guest star as the manager of a restaurant where Allen's Tv daughter Kristin applies for a job during an episode set to air in either March or April (13), according to Entertainment Weekly.

The former child star isn't the first Home Improvement actor to appear in Allen's programme - his Tool Time sidekick Richard Karn made a cameo in Last Man Standing during the show's second season.
