This Vulture article offers a rare and fun romp through American comedy history. As with any list of this nature, there are moments where you think to yourself...really...this made the list? Or you wonder why is there a 5 year gap between some jokes. Did comedy stagnate or did the people not reward the latest comedy delivery innovations? Comedy is subjective so I guess the best thing to do is make your own list adjustments.
If you too are a comedy nerd and are looking for a more reflective and deeper dive into American comedy history, I highly recommend Kliph Nesterhoff's book, The Comedians.
