James May describes a "Science Experiment" on Global Warming where he watched ice cubes melting in a drink and noticed the level in the glass didn't get any higher, which made him skeptical of sea-level rises. The ice displaces its own volume in the drink, and as the melting continues the ice displaces less and less volume as the melting water takes up more and more, so overall the level doesn't change. Sea-level rises are predicted because of melting land ice and because warmer water is expanded compared to colder water. (The same principle applies as when a metal sphere no longer fits through a similar-sized hoop when it is heated.)

Paul Merton refers to the film "There's something about Mary", but accidentally calls it "The trouble with Mary".

Whelks are not crustaceans, they are gastropods.

Paul Merton ridicules Ian Hislop for suggesting a "Feathery Snake", forgetting that the God Quetzalcoatl was a Feathery Snake.

The ears-caught-in-a-mechanical-rice-picker joke is from one of the Star Trek Original Series Episodes, not one of the movies. When the subject of Spock's ears comes up in "The Voyage Home", he starts wearing a headband.

Victoria Coren-Mitchell mispronounces Hasbro.

Katherine Ryan mispronounces vacillating.

Martin Clunes mispronounces sonorous.

Robert Lindsay mispronounces diplomatic.

Ian's reflection on the Covid Perspex Screens ruins several shots.

The brain of a clam is so simplified that it seems unfair to make fun of their flatulence, as they don't know that they are doing it.

Ian Hislop says "in cohorts with Lord Ashcroft" when he means "in cahoots with Lord Ashcroft".
