Garfield has always been a big money maker and enjoyed by millions of people. There are arguments by many about if the comics are even funny to begin with.
If you search web forums enough, you may find discussion about the characters in the strips, or even the mental issues of the main human character, Jon.
I've found sites where people have altered the message bubbles or even the entire comic strips trying to add their own style of humor.
Recently, I found a YouTube video of people dressed in Garfield and Odie costumes, and then the video went into them playing out an old Garfield comic strip. After that, the video changed into a Final Fantasy parody.

I figured someone had to put a lot of effort into making that, and there had to be more like it.
Well, today I found the source. There is a site called Lasagna Cat.
Here is the website for it:

There are several videos. Most of them are really weird.
