Lee Mack

The speed is obvious; the connection to somebody else’s last remark is what makes Mack valuable here. His keys story on Would I Lie to You?, from series eight, episode one, offers a compact introduction to a conversation becoming a game of follow-up questions. Notice how an objection supplies the next comic possibility. Choose his appearances when you want energetic verbal exchanges, and keep the surrounding discussion: isolated punchlines lose the chain of contributions that produced them.
