The Cover-Up
Very funny episode and we owe it all to
Dwight K. Schrute and his ability to exercise. When
Michael grows suscious that his new girlfriend
Donna (Amy Pietz) is cheating on him, he has
Dwight follow her, which leads him to her gym and thus his "exercise" program. Funny funny stuff. The epilogue at the end where he literally takes over the cycling class was a riot.
Also funny was
Darryl's prank on
Andy, getting him to believe that he would have to enter witness protection because he will become a whistler blower against Sabre for manufacturing faulty printers.
And yes,
Donna is cheating on
Michael.
