body: Basically, can I find a popular meme online and use it in a video-game that I am making money off of without giving credit or royalties to the creator / owner as often these are hard to find and people using these memes is so common.
  
  
  For example, there is a grumpy cat meme picture at <https://i.stack.imgur.com/fzJBP.jpg> that meme pages often use, can I use it?
  
  
  Meme pages often use and steal memes from each other without giving credit and then make money through ads and stuff. This seems to be internet culture so is it ok for me to "steal" and use memes and make money off of them?
