I like this article. Your constant use of Chevy Chase and jokes such as “Vegas Vacation was another video that Chevy Chase did, but many people have never seen it!” are funny. It could be funnier if you explain why everybody is happy that they are not Chevy Chase, instead why not write that everybody wants to be Chevy Chase. You also jump from one section to another without much continuity. How does Chevy Chase go from “Birth and Pre-SNL” to “Live from New York!…”? Sections such as “Birth and Pre-SNL” are also short. Add more detail to them, like talking about his childhood, etc. Also because Chevy Chase is mentioned so much in this article, make all the hyperlinks linked to Chevy Chase.
A good concept, since Chevy Chase is a comedian and this is a comedic article. To bring out its full potential you need to expand on what you have written. Write more about your sections.
Prose and formatting:
Put italics and bold for added emphasis. As is written down the bottom, “Change it so the text is proper paragraphs without the gaps between sentences and try to avoid lists. Otherwise, not too bad.” So fix that up.
Good images chosen, but I’m not sure why everyone doesn’t want to be Chevy Chase. You will need to explain that somewhere, such as making an image with Chevy Chase doing something embarrassing and writing "that's why no one wants to be Chevy Chase!"
Used the pee formula.
Overall it's pretty good. Make sure to fix up the bits mentioned above.
