Anthony Joshua could not contain his laughter when he joined Sky Sports' Johnny Nelson for a hilarious game of 'Splash Talk'.
Britain's world heavyweight champion held a gulp of water in his mouth while Nelson tried to provoke a laugh from 'AJ' with his humorous trash talk.
Joshua is teased about his entourage, that bitter rivalry with Dillian Whyte, and his reputation as a 'mother's boy' by the Sky Sports expert.
The tables are then turned as Joshua forces Nelson to lose his cool, and a mouthful of water, with joking references to the cruiserweight's ring career.
