Peter Willis was an entertainer and cross-dresser who appeared on Knowing Me, Knowing Yule as Fanny Thomas.
Willis was a former disk jockey who, according to Alan Partridge "[dressed] as a woman for cheap laughs". Despite this, he had seen some success as "daytime TV's favourite chef" Fanny Thomas, a character who continuously spouted innuendos, along with her catchphrase "Ooh! Pardon?". According to him, his mother was very proud of his work.
