S4E11 · Survivor Man

Complete story — includes the ending

When Michael is not invited to a company wilderness retreat hosted by Ryan, he decides to prove that he has the ability to survive on his own. Dwight drops Michael in the middle of a forest, and although told to leave, stays to prevent Michael from injury. When Michael almost eats poisonous mushrooms, Dwight jumps out to save him just in time. Meanwhile, back at the office, Jim, as the number two, decides to combine birthday parties for three members of the staff whose birthdays fall in quick succession. The plan, though, is poorly received by the staff, and Jim returns to having individual birthdays just as Michael and Dwight come back.
