15 years after his last appearance alongside his longtime TV costar, Tim Allen, in Home Improvement, Jonathan acted in four episodes of Tim's sitcom, Last Man Standing. The former teen heartthrob had been shadowing the director of Last Man Standing when he was asked to perform in the series. After Jonathan said yes to the request, Tim "was shocked, because...he's just shy," Tim said to Yahoo! TV in 2013.
"It was too fricking much," Tim added. "I'm an emotional guy sometimes. I just adore Jonathan. I adore all those boys [from Home Improvement]. ... I resist any kind of description, because it sounds cheesy, but it was adorable watching [Jonathan] there. It was so much fun having him on the set, but he's there a lot, anyway. Of course, I tell him he's probably just there for the craft services. I tell him he probably stops by, yeah, for shadowing, but then he just gets a turkey sandwich and goes home."
