Hilarious comedian and star of Comedy Central's new show "Big Lake" Chris Gethard went on "Late Night" Friday night and talked about his campaign to get Diddy's attention. Gethard explained to Jimmy Fallon about his comedy show at the Upright Citizen's Brigade theater in NYC, "The Chris Gethard Show," to which he and his Twitter followers have repeatedly invited Sean "Diddy" Combs to appear. Then, last New Year's Eve, Combs actually contacted Gethard and agreed to come, but nine months later still hasn't showed up. Fallon helped Gethard out by encouraging Twitter users to continue to harass Diddy with the unintentionally hilarious hash tag #diddygethard. If the Internet rallies together, he just might have to actually come through.
