Len Goodman was the head judge on Dancing With The Stars since the show's start in 2005, and he's had some memorable moments on the show. He sat on the judges' panel for every season; however, in 2020, he was unable to travel to the United States from the United Kingdom due to the COVID-19 pandemic. Because of this, Len had to miss out on the season, but made occasional virtual appearances throughout the show. He later returned for DWTS season 30 the following year.
