They're not on good terms:Knight Captain Kerr said:The Two Doctors:
The Doctor [http://reprog.files.wordpress.com/2010/04/11doctors-lrg.jpg] and Doc Brown [http://static3.wikia.nocookie.net/__cb20121024231110/epicrapbattlesofhistory/images/3/34/Doc_Brown.png] go on a fun time travelling adventure.
But on the Doctor Who theme, I want to see Captain Jack Sparrow meet Captain Jack Harkness[footnote]BARROWMAN![/footnote]. Oh, think of all the hamming to be had....
Aaaaanyway, I really want to see John Stewart (Green Lantern) team up with Jon Stewart (The Daily Show).
Following the "amalgam" theme a lot of people have done, I also want to see Tekkaman Blade [http://en.wikipedia.org/wiki/Tekkaman_Blade] the Vampire Hunter [http://en.wikipedia.org/wiki/Blade_%28comics%29].
Raddam vampires. That's a scary thought.
