Wait, THIS is how I find out?

It goes way back. His sister is literally older than the existence of Garfield.

I didn't know this until 51 minutes ago.

Can you edit this to retain the original caption but with the two fish just floating in the air?

That is possible. But it would have to wait. I have burritos to make and cutting boards to finish.

Ok guys I don't understand any of these comics. What is the joke?

Generally, you can remove Heathcliff and the joke stays almost exactly the same. The absurdist, Dada ant high joke remains intact. The titular character is not the main source of action. If removing orange cat and any references to him keeps the joke intact then it's a successful edit.

In this particular case, a little more action was needed and a new absurdist comic was created.
