Without a guest in dictionary corner the show would be rather dry,boring, not to say sterile.The guest spot can be quite revealing too.Just watch how Susie interacts with the guest,and her body language.Some she flirts with,some she engages(wordwise)with,and other she looks as if they are not there.The worst incident of ignoring Susie (and getting bad looks from her) was Jack Whitehall's father.He treated Susie as if she was a menial,with no intellect of her own,but it was fascinating to watch.I look forward to the guest,even if I don't completely like them.
