Surprised Patrick is a photoshop meme in which a cut out of the SpongeBob Squarepants character Patrick Star from the animated television series is superimposed onto different base images of various humorous contexts. In the images, Patrick always appears to be in a state of shock or bewilderment with his mouth agape.
