Garfield famously isn't a big fan of Mondays, but here's the specific reason he hates them. Garfield was created by Jim Davis and he made his comic strip debut in 1978. Garfield is a lazy, self-absorbed, lasagne obsessed cat who makes life something of a living hell for his loving owner Jon and Odie, Jon's dimwitted dog. Garfield's deadpan humor has seen the character remain popular for over 40 years and outside of the comic strip, he's appeared in numerous TV shows, specials and CGI movies, including Garfield And Friends and Garfield Gets A Life.
In an odd twist of fate, Bill Murray would end up voicing Garfield in the 2004 live-action movie. Murray replaced Lorenzo Music, who had voiced Murray's Ghostbusters character Peter Venkman on The Real Ghostbusters. Murray's role in the Garfield movie has become a recurring anecdote for the actor, as he claims to have signed on because he mistook screenwriter Joel Cohen (Cheaper By The Dozen) for Joel Coen (No Country For Old Men). He's since made fun of his Garfield performance in both Zombieland movies, but despite his evident distaste for the original he still returned for 2006 sequel Garfield: A Tale Of Two Kitties.
Garfield has many hates, including exercise, anything that requires effort and Mondays. Now there are many reasons people hate Mondays in real life, but for a spoiled cat for whom every day is basically the same, there shouldn't be any reason for him to single out a particular day of the week. On this front, Jim Davis once revealed to HuffPost this is exactly why Garfield hates Monday - it just reminds him of the emptiness of his existence and that he repeats the same cycle again and again without end.
Outside of the Garfield comics strip and the other mediums he's cropped up in, the tabby has become part of a creepy meme in recent years. This involves turning Garfield into something of a horror character, with memes like "I'm Sorry Jon I Was So Hungry" finding Jon trapped in his house after realizing Garfield has swallowed it. Other images involved Garfield being a Thing-like creature begging Jon for some lasagne, or issuing ominous warnings like "Bullets don't work Jon."
While there's certainly potential in the idea of a horror movie take on Garfield, it seems unlikely the next film from director Mark Dindal (The Emperor's New Groove) will head down that route.
