This is one of my favorite Series V articles yet! +1
I have a few suggestions to spruce up the article:
Both instances of "physically" could be removed and would improve the flow of the article.
"The french fry will demanifest after it is thrown" is saying that the fry demanifests the moment the burger throws it rather than when it hits another object.
Specifying how the SCP-4585 instances throw the fries is a good idea (telekinesis? growing a doughy appendage and flinging it?), because as it is now it doesn't specify.
"In the event that the meat of an SCP-4585-1 instance is completely separated from the rest of the rest of the hamburger" Duplicates.
Em dashes (—) should be used for the interruptions rather than hyphens (-); this one is a minor gripe, but it's standard.
"SCP-4585: Excuse me, but are you threatening to incapacitate Hamburg!" You could add a question mark here as well (to get ?! or !?), but their use is more up to preference than a standard. You could leave this one as-is, but I figured I'd point it out.
Not a big fan of this one.
It has been 0.87 years since I posted this, and on reread I have changed my novote to a downvote.
I really like this one, especially the fridge horror at the end when you realize that these silly hamburger people have been locked in a windowless room for 30 years. +1.
