Seth Rogen "Not Going to Answer" if Pot Was Real at MTV Movie Awards

Who got the biggest buzz at Sunday's MTV Movie Awards? Pineapple Express stars Seth Rogen and James Franco, who said they were smoking "fake weed" as they presented the award for "best summer movie so far." They joked that MTV chose them becaus...e only "two potheads like us" would be willing to announce such a weird category. As they pulled out a "huge fatty joint" and lit it, cameras pulled to a wide angle and stayed that way until the two left the stage. (See more outrageous photos from the show.) New York's Daily News wrote that the "sweet scent wafting through the Gibson Amphitheatre suggested the herb was real." Added Robert Downey Jr. (whose film Iron Man won): "Thanks for that intoxicating introduction." Rogen refused to reveal if the pot were real. "I'm not going to answer that question," he told the Daily News. Asked what was in the bag, Franco told the Associated Press, "I don't know! MTV gave it to us." He said MTV asked them to do the joke, even providing them with the script and fake weed. Before they went on, he said, "backstage there was this big commotion: 'You guys can't [do] that.'"
