TV Tonight: Alan Carr’s Great Secret Geniuses Competition | TV and radio

Secret genius

9pm on Channel 4

Alan Carr and ‘responsible adult’ Susie Dent team up to find some of the thousands of undiscovered geniuses in the UK. “[They] “They’re a really likeable bunch because they work on difficult tasks (one contestant successfully relies on a cha-cha chip) and viewers can play with them,” says hotel receptionist/drag queen CJ, who takes part in the first round with 11 other ‘normal’ people with very high IQs, including a shepherd who has taught a sheepdog sign language and a tree surgeon with four GCSEs because they work on difficult tasks (one contestant successfully relies on a cha-cha chip) and viewers can play with them. Carr, of course, is a ray of light as he delivers the news of who will advance to the finals in Oxford, so the battle of the minds begins! Holly Richardson

Sarcasm of the week

9 p.m., TLC

This topical satire was much lamented when the BBC canceled it in 2022, after 17 years on the air. Now TLC has revived it, with host Dara Ó Briain and regular participant Hugh Dennis returning.
