Greg Davies and Alex Horne return to host the show with rookie rivals Alan Davies, Desiree Burch, Guz Khan, Morgana Robinson, and Victoria Coren Mitchell.
The contestants have a mountain to climb as they must find a way to prove they can handle some teamwork; Morgana Robinson inspects suspect doggy bags and Guz Khan slaps a space hopper.
Taskmaster Greg Davies struggles to contain his scorn as Desiree Burch does something inexplicable with sand; Victoria Coren Mitchell draws an exploding cat; Alan Davies hurts himself with a rubber band.
A fiendish riddle fires up Alex Horne; Morgana Robinson drenches herself in peas; Victoria Coren Mitchell learns a new skill; Desiree Burch makes a political statement with jam; Alan Davies piles on the sunglasses; Guz Khan pens a song.
For the 100th episode of Taskmaster, Greg Davies, Alex Horne and their merry band of comics celebrate the only way they know how: with tasks involving plastic balls and flapjacks.
