Underpants are on sale at the convention. So literally, Professor Y Fronts.
As the title suggests, a parody of 1960's Doctor Who. Professor Y travels in space and time in a red phone box. His enemies include The Zybok's (war cry 'O-BLIT-ERATE') and The Mechanomen.
Professor Y's costume contains elements of previous Doctor Who costumes - cravat (Tom Baker), pullover and spats (Sylvester McCoy) and tartan trousers [Patrick Troughton).
When Sister Boniface daydreams about being in the programme, she says 'My giddy Aunt!', the catchphrase of the second Doctor Who, Patrick Troughton.
Marc Silk (Zybok) was in a S11 episode of the audio series Doctor Who: The Fourth Doctor.
