Because their vacation pictures were clearly more important than the propagation of an entire species, a mob of tourists at Costa Rica's Ostional Wildlife Refuge decided the annual march of the sea turtles was the perfect time for some... sea turtle selfies!!! Only problem: the turtles didn’t agree. So when the turtles arrived on shore and attempted to lay eggs on the beach like they’ve been doing for, you know, ever, they were met with a horde of gawking tourists. And as any creature might do in the same situation, they immediately turned back into the ocean without laying said eggs.
Another possibly ill-advised place to take a picture of yourself? In the streets of Pamplona, whilst being chased by a bunch of angry bulls. Sure, just DOING the running of the bulls might be considered dumb by a lot of people, but at least if you're “running,” your chances of survival are pretty good. It's not called the “Standing in the Street Taking Selfies of the Bulls” for a reason.
