Joel Spence, Colton Dunn, and Johnny Meeks join Matt Besser for this week's episode of improv4humans. They perform scenes about a ragtag group of retail freedom fighters, children's books that teach harsh life lessons, and a town up in arms about progressive snowmen. Later, they set unrealistic goals on their wish-boards, visit a shoe outlet that enforces a sock policy, and rescue their dogs from a rhino's headlock. This episode is brought to you by Blue Apron (www.blueapron.com/improv) and HBO's "Crashing."
