Michael is preparing to leave Scranton, but not without hosting one final Dundies. He elects Deangelo to be his co-host so that someone can keep the tradition alive after he leaves. The problem is that Deangelo can't perform in front of people.
After struggling through most of the Dundies at a fancy restaurant, the manager kicks them out for Deangelo throwing up too much, and Kevin coloring on the table cloths. The group heads back to the office where they finish the Dundies, and Michael's employees serenade him with a touching song.
