(For convenience, let's call your friend "Alice" in the following.)
You fetch references (branches or tags), not commits
I would like to pull the changes from that commit into my project.
Is it not possible to pull a commit from a different project?
Strictly speaking, you don't fetch commits; you fetch references (branches or tags). If you're interested in a particular commit that exists in Alice's repo but not in yours, you'll need to fetch a reference whose ancestry contains the commit in question from Alice's repo.
Use a valid git fetch syntax
Using [...] throws the following error [...]
The command you're using,
git fetch <remote-url> <commit>
is not a valid git fetch syntax, hence the error you're getting. The syntax you want to use is
git fetch <repository>
where <repository> is a remote, i.e. a nickname under which your local repo knows Alice's repo. You may want to be more specific and also add a refspec at the end of this command.
Edit: As pointed out by torek in his comment, you can also use a naked URL, without configuring the remote in your local repository, but that's probably not what you want to do, here.
Add Alice's repo as a remote first
git remote -v gives me the following [...]
The output of git remote -v indicates that you haven't added Alice's repo as a remote of your local repository yet. You need to to that before you can fetch from it:
git remote add alice https://github.com/cvandermeer/wisemonkeys.git
Fetch and find out more about the commit of interest
Then run
git fetch alice
to fetch everything you don't already have from Alice's repo. You can then run
git name-rev f70bcfd75a498ed9159b6e5313e306166fc3df62
to identify a reference from which the commit is accessible, and
git show f70bcfd75a498ed9159b6e5313e306166fc3df62
to print information about the commit and decide what to do with it (cherry-pick it, merge the branch it's on into one of your local branches, etc.).
