The first team task of the series brings the usual awkwardness, but also the joys of Stevie Martin inventing a new way for humans to move, and Fatiha El-Ghorri sweeping the lawn with a small broom. Elsewhere, Rosie Ramsey has a visceral reaction to mental arithmetic, Mathew Baynton strikes his own face with a grape, and Jason Mantzoukas destroys a shower.
