Square Root of Minus Garfield/YMMV


 * Discredited Meme: The "Garfield [something that sounds like minus] Garfield" bit after one use too many. It was officially axed when they made a strip with the Terminator going back to stop the meme's creation.
 * Genius Bonus: Many strips require you to be a fan of a certain work to get them, such as The Wall, My Little Pony Friendship Is Magic, or The Angry Beavers.
 * High Octane Nightmare Fuel: Outright Lampshaded in "Nightmare Fuel Garfield"
 * Those tiles...
 * Moment of Awesome: Strip 625, which took an Overused Running Gag and effectively terminated it.
