Lasagna Cat sets out to make Jim Davis "tribute" videos, and among the vast "Garfield isn't funny but here's how we'll try" section of the internet, this is the funniest take on it I've seen so far.
Each video reenacts a Garfield strip, then showcases a music video custom-made to fit the theme of the strip (often, if not always, more hilarious than the reenactment itself). Out of the whole list there's not a bad one among them.

"YEE-HAW"
"I'M USING THE CAT BRUSH"
"Garfield, all you do is sleep"
Also check out 04/04/2001, 05/16/1985, and 1/19/1987. And the rest of them
EDIT: The first video is actually the best and I can't believe I forgot to mention it. Especially if you're a Final Fantasy fag.
