The ongoing feud between Conan O'Brien and Newark Mayor Cory Booker ended last night with Booker appearing on the show and Conan donating $100K to Booker's charity (video 1, 2). Conan also set up a "Newark Joke Jar" and promised to add $500 any time he made a joke at the city's expense, the Star-Ledger liveblogged (really). The feud began when Conan made a joke about health-care in Newark—"The health-care program would consist of a bus ticket out of Newark"—and resulted in his being banned from Newark Airport. And thus ends the scandal that never really was because Letterman had to go and ruin everything.
