Jimmy Fallon popped by Late Night to address yesterday's news that he would be taking over for host Conan O'Brien in 2009, an announcement greeted with wide-eyed, Christmas Eve wonder by the three TV executives who hired him, and, "Wait—that annoying dude from those DJ sketches on Saturday Night Live?" from everyone else.

In the name of science, we've hooked ourselves up to a series of vital-sign monitors, and, as a team of white coats monitors our progress through this Fallon anecdote about proposing to his wife, we'll update you on our progress:

14 seconds: Slight increase in heart rate, pupil dilation. Shortness of breath. Why can't this guy sit still?
27 seconds: Dry mouth. Palpitations. Pulse up to 112 bpms. Carotid artery bulging. Put your goddamn hands down and just finish the story.
1 minute 15 seconds: Profuse sweating. Head the color of a purple cabbage. Face spread back as if subjected to a NASA 20-G Centrifuge Machine.
2 minutes 8 seconds : Loses consciousness at first mention of "Barry Gibb."
