Les begins a new series, only to find there's a guest missing on the panel. Can Blankety Blank's warm-up man (and "Hi-de-Hi!" star) Felix Bowness step in to save the day?
"I couldn't fault your performance tonight," Les tells a losing contestant, "there wasn't enough to form an opinion." Meanwhile, Bernie Winters has an eye infection, so has to spend the whole show wearing sunglasses.
Three long-standing regulars make their final appearance in this edition, as Janet Brown, Alfred Marks and Sabina Franklyn sit on the panel for the last time.
A low-scoring game has Les wondering if the show has the worst-ever contestants on it. Occupying the panel are guests including Linda Lusardi, Barry Sheene, Gary Wilmot and journalist Lynda Lee-Potter.
The centenary year of aluminium gets celebrated with a selection of aluminium-based prizes. Plus, with Fenella Fielding, the panel gets a celebrity guest who is so bad she insists herself that they should have got someone else.
A chaotic edition, with disruptive contestants, Les at his most abusive, and the return of Lennie Bennett to the panel. There's also the sole appearance of DJ Dixie Peach, along with a contestant who Les insists is Little Richard.
Madhur Jaffrey and Miss UK Mandy Shires make their sole appearances on the panel, while William Gaunt makes his first. Yet Les is so dismayed with the quality of the panel, he decides that the best thing to do is to shoot them all.
Les is at breaking point with the show's low budget, while the questions are some of the most obscure yet. New to the panel is Rustie Lee, while among the returnees is Les's old co-star Roy Barraclough.
Les oversees a very high-scoring game, though when the producer is monitoring viewers who switch off after seeing the panellists, things don't go quite so well.
The Krankies return to the show for the first time since series three, but with Jeanette as herself, not in her guise as Wee Jimmy. Appearing for the first time is comedian Tom Pepper, while there's also the sole appearance of Sneh Gupta.
"I'm getting no help from you, I'm getting no help from the producer - the panel's a waste o' time. The contestants look as though they've just been dug up. What'd you expect from me, eh? I'm a person."
Les welcomes Charlie Williams to the show, and Derek Guyler returns for the first time since the second series. But Derek and Aimi MacDonald both struggle to find a pen that works.
This week the female panellists are Beverley Sisters, and the males weathermen. Les introduces John Kettley, Michael Fish and Ian McCaskill by assuring viewers that "They are to weather forecasts what Long John Silver was to tap dancing."
Les isn't happy with the week's panel, telling the producer "They're has beens before they was ones." The contestants don't please him much more, being told they'd be lucky to get no points, and the questions are some of the rudest yet.
The panel storm off in disgust when Les criticises them, forcing Les to assemble a replacement panel. As it's the last show in the tenth series, Les also brings on a special surprise waitress to toast the audience.
