David Guintoli and Sasha Roiz — who star on the TV show “Grimm” as Detective Nick Burkhardt and his boss Captain Sean Renard, respectively — joined the Naked Bike Ride in Portland, Oregon last weekend.

The TV series “Grimm” is set and filmed in and around Portland. The Roiz explained the two stars kept their pants on for the World Naked Bike Ride to avoid controversy that could endanger their jobs.

The photo came initially from Twitter somewhere and was modified at TMZ.com.
