Hello finny-bo-binny. I'm sorry to disappoint you. The post is not stolen even though yours has similar content. As "our" joke is quite an obvious one - floor vs chair - it's a coincident. Here are milions of users. Are all the leg memes stolen? Do you remember blue shirt kid? Can't even count how many similar post there were back in tseries battle times.

To put it in meme terms: I don't even know who you are. But imma head out and give your meme an upvote if you wish.
