As a person who has a lot of fun writing and designing memes, I can tell you that there are two important rules to creating memes.
Number 1: Have a good original concept. Memes are like VHS tapes. If you make a copy of a copy of a copy, eventually you end up with a garbage copy.
Number 2: For crying out loud people, learn some basic grammar and sentence structure. Take your time and proof read your text. Nothing can ruin a good concept quicker than bad grammar or forgetting a word.
Take for instance the meme below from mothersquotes.com. What should have read as sweet motherly advice, actually comes off sounding like tips from a serial killer.
I'm pretty sure the first line in that meme should read, "Be careful who you open up to...". Instead it says, "Be careful who you open up".
Apparently, this meme was made by Dexter. Kinda makes you wonder what the moms at mothersqoutes.com find entertaining.
Creepy.
