Best reaction possible? BEST REACTION POSSIBLE!
If you're going prank a person by pretending you're trying to end their life with a car bomb, that person has every right to beat you until you bleed into your pants. That's why you prank helpless people, or at least someone that can't pound you to death.
These pranksters are the same guys that went around Miami terrorizing people as zombies. Unlike that hoax, this prank resulted in the bomb squad showing up and the arrest of one of the pranksters, Vitaly Zdorovetskiy. Who, by the way, was SHOCKED that someone would call the bomb squad for a prank involving a hitman trying to kill someone with a bomb. He said, "The bomb squad came. Can you believe that? 'The bomb squad came for this prank. It's unbelievable how law is these days."
Yes, it is unbelievable how the law takes bomb threats seriously these days. Shame on those f*ckin' squares.
