Like what lesbian_potato did, take a screenshot of the little menu below the meme where you can choose to upvote. If the upvote arrow is green, then Ill see you actually upvoted it, and do what I promised in the meme.
Just make a meme, put the meme template as a white background, click add image, and it'll take you to your files, just find the screenshot, click it, and then click add image and it'll be added. Fit the screenshot to cover up the meme.
