Ranked joint 57th with 6.34 million viewers, tied with Ellen MacArthur: Sailing through Hell (2001).
Jeff Stewart reveals that he's dyslexic when he shows one of his answers. After a sympathetic response, he says that it "doesn't need an 'ahhhh', it hasn't held me back".
There are a number of moments in this episode where the "family viewing" remit of the series isn't strictly adhered to. Incidents include Jeff Stewart pretending to mishear "aural" as "oral" to make an innuendo, and Lily talking about having seen a horror film called "I Spit On Your Gravy", thinking it was about cooking. As such a film doesn't exist, the joke would only make sense if the audience knew she was making a pun on the title of "I Spit On Your Grave" - a movie which would be highly age-inappropriate for Blankety Blank's Sunday 6:50pm timeslot.
