The scene was amazing.

After a radical Islamic terrorist went on a stabbing rampage on London Bridge on Friday, two brave bystanders went after him.

One man grabbed a fire extinguisher, while another grabbed the best weapon he could find — a huge narwhal tusk that was hanging on the wall of the nearby Fishmongers’ Hall.

Video footage shows the attacker running across London Bridge wielding two kitchen knives, before he was confronted by the two heroes.

Then this happened.

The attacker was later shot and killed by police.

Queen Elizabeth II, in a statement, praised the men’s bravery. “I express my enduring thanks to the police and emergency services, as well as the brave individuals who put their own lives at risk to selflessly help and protect others,” she said.

By the way, if you’re wondering, narwhals grow to as big as 3,500 lbs and can live up to 50 years. They grow a massive tusk, or horn, through their upper lips that can stretch up to 10 feet long.
