Get It Off Me!

An event whereupon some hapless fool makes the horrible blunder of provoking something small and seemingly harmless (and sometimes even downright adorable looking) into attacking them. Often with shocking effectiveness, and often causing the victim to run around in circles screaming "GET IT OFF ME! GET IT OFF ME!"

Though used mostly in a comedic setting, this stock phrase is highly versatile with examples seen even in horror genres, ranging from comedic relief to break the tension to examples of outright nightmare fuel.

It's also very much Truth in Television for almost everyone at some point.

Comic Books

 * When IDW acquired the rights to Mars Attacks!, they got the brilliant idea to make a crossover with G1 Transformers... in which Megatron gets shrunk by the Martian leader. Naturally, Starscream decides to try and take advantage of the situation.  It goes just about how you'd expect it to, with the added bonus of Soundwave frantically trying to revert Megatron to his original size to stop the carnage.

Fan Works

 * In A Matter of Romantic Chemistry, the third installment of the Ranma ½ fic series Tales of Ranma and Ranko, Ryoga and the soul of the piglet whose body he turns into are given separate physical existences by a Magic Mirror. P-chan, it turns out, is less than happy about having been relegated to a passenger in his own body by Ryoga's far more powerful personality, and the first chance he gets attacks a transformed Ryoga (who still turns into a piglet).  When Ryoga is restored to human form in the midst of the two piglets' tussle, he finds P-chan clamped firmly to his finger and yells "Get it off!  Get it off!"

Film

 * An utterly nightmare inducing example can be found in The Mummy (1999), where a species of flesh-eating scarab beetles exists to protect artifacts and tombs, and attack as individuals or swarms.
 * Deuce Bigalow: European Gigolo has a hilarious example where a guy taunts a cat and gets clawed in the crotch.
 * Seen in Austin Powers when Austin gets in a fight with Mini-me. On top of clinging to Austin like white on rice, he even bites Austin the nuts and hangs on for dear life as Austin tries to get him to let go.
 * Monty Python and the Holy Grail. You know the scene.  "We'll not risk another frontal assault.  That rabbit's dynamite!"

New Media

 * "Get it off!" and "Get it off me!" are frequent themes/subjects for Memetic Mutation and Image Macros.

Video Games

 * Steiner in Final Fantasy IX cannot stand oglops (essentially jumping beetles), and this is his basic reaction when he accidentally breaks open a bag full of them.

Western Animation

 * SpongeBob SquarePants has several examples. Among them:
 * In one episode a sheet of paper adheres itself to SpongeBob's face the moment he walks out of his house and he panics, crying "Get it off of me!"
 * In another, Patrick is swarmed by musical notes (It Makes Sense in Context) and yells "Get'em off me!  Get'em off me!"
 * In yet another, Squidward gets a gelatinous mass of eyes and tentacles deposited on his head and reacts accordingly.
 * In The Simpsons, Barney Gumble reacts to unfiltered sunlight in this way.
