Inquisitive sloth photobombs tourists in Costa Rica4/5/2012
Sloths are notoriously slow and lazy, but somehow an agile one managed to drop down into the frame of this photo just before a bunch of tourists in Costa Rica snapped the shot, carrying out what might just be the cutest animal photobomb ever. To no one's surprise, the pic of the mischievous mammal has gone viral overnight. It isn't the first time an inquisitive animal has captivated an audience with its photo antics. In 2009, a squirrel achieved similar fame when it jumped into a couple's picture at a national park in Canada.
