The Late Show with Stephen Colbert promises to be a good one tonight — with Nick Offerman, Wayne Gretzky and Morgan Spurlock as guests.

Parks and Recreation star Offerman is currently promoting his newest book, Good Clean Fun, which discusses the ups and downs in the world of woodwork at his Offerman Woodshop and includes tutorials.

Offerman has been a fan of woodwork ever since learning the basics from his dad, grandfather and uncles — and the craft helped him pay his way through the early days of his acting career.

And Super Size Me star Morgan Spurlock will be on promoting his chilling new film Rats, which delves into the history of rat infestations around the globe.
