Imagine: you come across a meme, and people are upvoting and liking it, seemingly having a great time, and you're incredibly confused about what's going on.

The general idea of memes is that people should understand them (unless they're intentionally incomprehensible, which is a different story). That's what makes coming across a meme in the wild you can't understand so frustrating: surely someone gets what's happening here, and it's not you.

Luckily, the subreddit /r/PeterExplainsTheJoke has become the sub to deposit inscrutable memes and hope a kind stranger explains what's happening. Here, we've compiled 24 popular images dropped into /r/PeterExplainsTheJoke that baffled internet users.

Think you know your meme? See how many of these mysterious memes you can actually understand. Some require knowledge of physics, others SpongeBob, binary code or some good, old-fashioned pun-deciphering. Good luck!
