I think it was last week or sometime during the holidays that I wrote about Jimmy Fallon quietly being told that he was being considered to take over for Jay Leno when Jay's contract with NBC ended in 2014. I said then that there was no way that Leno would ever step down. Ever. Ever. Like a Taylor Swift song ever. Turns out that Jay just wanted to crush Jimmy's spirits like Jay crushes the spirit of anyone who ever wanted to ask a celebrity a real question. Jay has now extended his contract well beyond 2014 and will presumably not leave NBC until they carry his dead body off the stage. That will be necessary because no one will probably notice the change in his personality.
