Series 20 (2020)

This series is composed of unaired episodes as a result of the COVID-19 pandemic. The first two episodes were recorded in late 2019 to accommodate Rachel Riley's maternity leave, made obvious by the fact she still appears 8-months pregnant in these episodes;^[4] the third episode was originally filmed in early 2019 as references were made to Richard Ayoade's role in the "recent" film The Lego Movie 2: The Second Part; and the fourth and fifth episodes were Best Bits specials that were originally assembled in 2018. The Christmas Special was also filmed in 2019, prior to Riley's pregnancy.
