When Jim swears he didn't break his diet with a trip to Burger King, the industrious apprentice-assistant (and now private detective) Kyle comes to the rescue.

"Hope you don't pick your nose, Jim, I'm gonna to see it all," says Kyle as he installs a hidden camera in Jim's car. Video footage doesn't lie. Check out the actress's reaction.
