Leave it to a monkey to make the best possible expression in a zookeeper's selfie.
In a perfectly timed pic (which the photographer claims wasn't photoshopped), a Sulawesi macaque at Nebraska's Henry Doorly Zoo and Aquarium photobombs a zookeeper, proving that animals are still the best photobombers around.
But our favorite part has to be follow-up pic, in which the zookeeper snaps herself turning around to face her photobomber, suddenly the epitome of innocence. We all know what you did, you rascal!
