A comma is used as a short pause to create meaning to the words you are saying, where you put the comma depends on what word in the sentence you wish to highlight the most
in my opinion i would put the comma in one of two places
<span>The long winding road, was dark and ominous.
</span><span>The long winding road was dark, and ominous</span>
Just based off of my common knowledge of humor, I would say personally that "1. Is Rover really any brighter than a hamster, a chicken, or that kid who's always eating Play-Doh?
" supports the idea that the informational text uses a humorous tone.
