Desiree, Guz and Morgana invent GuzBall
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Guz initially suggested he watch Desiree and Morgana hit each other with bats, leading to the creation of GuzBall where Desiree and Morgana threw balls at Guz whilst standing on one leg. During their commentary, they played characters called Rod (Morgana) who was the Scottish lead, Rodders (Guz) who was a former player and Rodney (Desiree). They received 5 points each.
