WATCH: ‘You wanna f*ck with me?’ Vape shop owner fights back against armed robber in the best way

An armed robbery in Oregon went awry when the robber declined to "fuck with" the owner.

The owner of Str8vaping in Gresham, Oregon, was working the counter when a man wearing a blue mask and holding a large knife came into the shop.

"F*ck you, dude!" the owner yelled. "You wanna f*ck with me?"

"No, I don't want to f*ck with you," the robber says, meekly.

"You better f*cking run!" the shop owner says, chasing the would-be robber.

The video is so absurd that you might think it's fake.

Not so, the shop says.

"That's 100 percent real my friend," said a man who answered the phone at the shop. "We've been broken into before but we've never had anyone try to rob us."
