“I don’t like goodbyes – NBC does – but I don’t care for them,” an emotional Jay Leno said, kicking off a star-studded final broadcast show as host of The Tonight Show. “Tonight is our last show for real. I don’t need to be fired three times — I get the hint,” Leno joked to a friends-and-family studio audience as he ended his 22-year run Thursday night. It’s his second very-last-time-as-host — having been pushed aside in 2009 by NBC to make way for Conan O’Brien, who lasted seven months.
