What happened to the unicorns? In a shocking move that has evolutionary biologists around the world dropping to their knees in defeat, the brilliant theorists at French advertising agency BETC Paris have found the answer. And boy is it ballsy. 

"We had some rather surreal discussions on what unicorn [testicles] actually look like," says agency president and chief creative officer Stéphane Xiberras. "We thought about doing something a bit … unexpected. There was talk of [making them] furry with twinkling stars. But in the end we opted for a pair of 'classic' horse [testicles]." Slow clap BETC ... slow clap. After all, no species (even the magestic Equus unicornis) can survive the test of time without a viable population!
