Rainn Wilson kicked off season two of HGTV Canada’s “Celebrity IOU” with a bang.

The actor, known for his beloved role as Dwight Schrute on “The Office”, joined HGTV superstars Drew and Jonathan Scott to completely renovate his son’s former nanny’s home as a thank you for all of her hard work and dedication.

According to Wilson, their nanny, Leslie, has stayed a part of their family even now that his son, Walter, now 17, is now a teenager. Wilson shares Walter with his wife Holiday Reinhorn.

“We are so grateful that Leslie has been in our lives and helped raise our son,” Wilson said in a preview for season two of the hit series. “And we’re so happy to be able to offer her this home renovation, thanks to the Property Brothers. I hope her family loves it and enjoys it. She has made our lives so much richer.”

“Leslie gave so much love to our son, Walter,” he later added. “To watch him be nourished and flourish — there’s no more priceless gift than that.”

Wilson also revealed he wanted “to bring a little of the Dwight Schrute flavour to this demolition,” before telling viewers: “I’ll be right back.”

He then returned, bare-chested and holding medieval weapons, asking: “Ok, what do you say we get medieval on this kitchen?”

“In my entire construction career, I have never seen someone show up topless with medieval weapons to do demo,” Jonathan admitted.

Zooey Deschanel, Allison Janney and Justin Hartley will also join the Scott brothers to surprise their loved ones for season two.

“Celebrity IOU” returned on Jan. 4 at 9 p.m. ET/PT on HGTV Canada.
