Pair of Kings (2010)

S3E18 Yeti, Set, Snow

Boomer realizes that he and Boz lack the shared brotherly memories that he has with Brady. Determined to change this, he decides to recreate a childhood ski trip. However, when Boomer arrives at the site he has chosen for his resort, he discovers it's inhabited by Yetis. Rather than driving them away, he takes it upon himself to teach the Yetis how to live in a more civilized manner.
