For the first time since the wrap party, the entire cast of 30 Rock assembled on Late Night with Jimmy Fallon last night. What started with Tracy Morgan’s perfectly adapted cover of … wait for it, Boyz II Men’s “It’s So Hard to Say Goodbye to Yesterday,†developed into a sweet dishfest on the mistakes averted, the tricky scripts, and the tears, oh, the tears. Apparently, the whole crew had taken turns crying at each cast member’s final shot on the finale set scheduled to air Jan. 31. “In my last shot … it was me with no lines, running on a treadmill for five seconds,†Tina Fey said in her nuanced spoiler. “I was like crying on the treadmill.†Tracy Morgan recalled having to put a stop on Lorne Michaels who had originally intended to name his character Boo Boo Jordan; Alec Baldwin remembers meeting X-rated-Tina at the gym; and Jane Krakowski commented on the lightning-crack-speed of the script through the seasons. They made such a cute, delightful bunch, thank God for syndication. Enjoy their camaraderie in the video ahead.
