NBC Jay LenoJay Leno isn’t letting up. On Tuesday night the The Tonight Show With Jay Leno host took another shot at his NBC overlords: “A 28-year-old woman from Serbia has a rare brain condition where she sees everything upside down”, he said in his monologue. “The good news? She’s now been given a job at the White House as President Obama’s economic adviser. Isn’t that crazy and unbelievable? She sees everything upside down. In fact, she thinks NBC is at the top of the ratings!” The joke comes a day after Leno called NBC’s executives “snakes” (watch it below) and brings him back to the target that sparked his recent feud with NBC’s Bob Greenblatt: NBC’s abysmal ratings.
