As Jay Leno’s tenure draws to a close at the Tonight Show, his years there will soon be left to the historians—those duty-bound to ensure humanity remembers it has seen this, that it has heard about this. And now researchers at the Center for Media and Public Affairs have gotten an early jump on immortality by compiling a list of the most frequent targets of Leno’s satirical barbs during his two decades as host, up through his January 24 show. Sadly, it seems that under those constraints, Jay Leno was only able to make 4,607 jokes about Bill Clinton—even after NBC wisely reinstated him, knowing his work was not done. Fortunately, Leno still has until Thursday, and Bill Clinton still got a blowjob that time.
