Sometimes the most obvious things are completely invisible. Inspired by Sesame Street's iconic sketch "One Of These Things", Bored Panda has compiled a hilarious list that will not only brighten up your day, but - like the original - check your attentiveness as well.
The idea is pretty simple: each of these images contains an "intruder" that simply doesn't belong there, and your mission is to find them! So take out your magnifying glass and remember what you've learned while reading Sherlock Holmes because it's finding Waldo all over again. Scroll down to search for things that don't belong in the pictures, and upvote your favorites!
