There's a famous scene from the movie Hot Fuzz where the characters fear that an old sea mine will detonate, so they run about 20 feet and jump over a low wall. Lucky for them, it doesn't explode, but after seeing this World War II sea mine explode on the beaches of Katwijk Aan Zee, Netherlands, I think they'd be very, very dead.
Construction workers found the mine lying on the beach, according to nieuws.nl, and used the bucket of an excavator to move the giant goddamn bomb right along. Because Dutch excavator drivers are braver than you.
The local bomb squad decided to detonate the mine right there on the beach rather than take the risk of attempting to defuse it.
Next time you see an old bomb from World War II, run. Run like hell. And run further than 20 feet.
