This week's guessing game highlights include trying to predict how many plums it takes to measure John's man-spread in 'Guestimation Unknown', who has adopted a pet llama in 'Objectification' and Kammy trying to spell some not particularly long words in 'Spells Like Team Spirit'.

But all these games count for nothing if the teams can't guess who is in John's Mystery Box from the clues revealed throughout the show.
