The Conan O'Brien show has gone all-in for this year's Comic-Con International, plastering the San Diego airport with advertisements for the Conan-themed line of Funko Pop! vinyl figures, running commercials hyping his attendance and rolling into town Mad Max-style.

Now, he's celebrating the week with the early, "illegal" debut of the new trailer for "Batman v Superman: Dawn of Justice."

Well, not really.

Conan sends up the anticipated Warner Bros. film in a parody which finds the titular heroes taking each other on in the dirtiest of dirty fights: a battle over property lines. Superman enlists the aid of Bane in supporting his argument, declaring "no, no, no, no, no, no, no, no, Batman," while Batman brings mother jokes into the proceedings.
