A photo of two friends has been trending on social media for years after viewers spotted a hilarious mistake.

We all love to take photos with our best friends and family members from time to time. And when we get bored, we might use the opportunity to make goofy faces or poses while posing for a photo.

Two friends, however, decided to take things to the next level. Check out their photo above and tell us if you can spot anything unusual.

As you’ve probably realized by now, there’s a whole extra set of hands in the picture! Who do the two hands that are placed on the shoulders of the man on the right belong to?

We suspect that there’s another person hiding behind the guy on the right. What do you think is going on here?

Here comes our second visual challenge. This time, it’s your job to help the groom and bride find out what’s going on in one of their favorite snaps from the wedding.

As Kevin Matthew Dennis explained on Reddit, he and his wife Christina were shocked after learning there’s something terribly wrong with one of their favorite wedding photos.

Take a look at the photo and see if you can figure out what terrified the couple!

If you focus on the empty space between Kevin and Christina, you will spot a creepy-looking figure. Up until this day, no one, including the couple, managed to find out who or what the thing in the photo is.

Was it one of the wedding guests that decided to photobomb the pic? Or was it perhaps just clothes as some users suggested? Let us know what you think!
