On part two of this season's finale, the guys get their groove on with the Gnawa Tribe and bond over a campfire in the Sahara Desert.

On part one of this season's finale, the guys head to Morocco in Africa, where they take a camel ride through the desert, get lost in a Marrakesh bazaar, have a special dinner (each making one last wish for the trip), visit a youth boxing gym, and ride scooters into the Moroccan desert.

Henry Winkler, William Shatner, Terry Bradshaw, George Foreman and Jeff Dye explore Madrid, Spain: experience an altered version of the Tomatina Festival, learn the art of bullfighting with matador lessons, embark on unique culinary adventures, try flamenco dancing, and get kicked out of Tavera Monastery.

The guys enjoy the culture of Barcelona, Spain and embrace their artistic sides: joining a parade of giants; tango dancing; a lunch of traditional Spanish delicacies; Terry shows Barcelona what a full moon in the middle of the day looks like; Henry bares it all as a nude model for an art class; and becoming part of a human tower.

The guys head to Berlin in the hopes of finding Henry's roots.

Later, Henry makes a powerful discovery about his family's past that changes his life forever.

Bill's in the driver seat as he takes the guys to Lithuania, a place they've never planned to go but it happens to be where his parents grew up.

Bill's big plans lead the guys to stay in an uncomfortable haunted castle and an unpleasant visit to a neighbor country, Russia.

A search of Terry's Viking roots uncovers a "Viking Island" that leads to a series of challenges that aren't for the faint of heart.
