Casanova

In 1580 Venice, after the Eleventh Doctor realised that Casanova wouldn't be born for another 145 years, the Doctor told Amy Pond and Rory Williams that he didn't want to run into Casanova, as he owed him a chicken in a bet. (TV: The Vampires of Venice) He later claimed to Valarie Lockwood the chicken was repayment for Casanova helping thwart a Sontaran invasion. (AUDIO: The House of Masks)

On Red Rocket Rising, Lucie Miller described the Eighth Doctor as "that bloke dressed like Casanova". (AUDIO: Blood of the Daleks)
