Get it? Because David Tennant played the Doctor and Casanova? Heheh... he... oh fine. So it isn't funny. Just an odd comic that popped into my head some years ago that I felt the need to redo. Really I just wanted to draw Mr. Sexypants.
Okay, so the Tenth Doctor is Casanova, and the Eleventh Doctor owes Casanova a chicken... Does that mean the Eleventh Doctor met the Tenth, saved the world with him, did something so he owes him a chicken, while managing not to cause a paradox?
You know what the best part about this is? That if you actually read Giacamo Casanova's memoirs, he apparently DID meet Madame De Pompadour! There was no mention of smex, but according to the memoirs they met socially and she gave him a present of perfume. It COULD be some really amazing crossover.
