I collected these from Jimbob's official Facebook page, here: http://www.facebook.com/madebyjimbob

There are a lot more there, I just grabbed the COVID memes. He has also collected his recent art into 3 books, Savage Memes 1,2 and 3.
His website: http://madebyjimbob.com

Can also find these posted here: https://www.arkhaven.com/comics/comedy/savage-memes

These are in the order in which they have appeared on Jimbob's Facebook page (and/or elsewhere). A couple of them might be older. He started in on these in March of 2020 and they have continued to come out into 2022...
