Conan O'Brian's last show on NBC was on Friday night. Unfortunately due to a bout of insomnia the night before I couldn't stay awake for the whole thing. However I do remember seeing Beck at one point, but that may have just been a fever dream. Now all we have left are YouTube clips of O'Brian during his time on NBC, whether it be the short lived Tonight Show or Late Night.
Hopefully he'll turn up eventually, once the period he's not allowed to host a show expires. The rumours still is that he might land on Fox where he once worked as a writer for The Simpsons and wrote one of the all time best episodes, the one featuring the monorail.
