I'm surprised this hasn't been posted yet. It really shouldn't be funny, but by gods it's hilarious... YouTube - Man shot twice in Kings Cross attack
If I had to guess I would guess it's because the way the girl said "chk chk boom" as the title of the thread suggested, but yeah, English accent doesn't automatically make everything funny... I wonder if the guy survived the gun shot?
For some reason people tend to think my English accent is Australian. Never could figure that out as I certainly don't sound it as far as I can tell. Anyway, I can't see any hilarity factor in this video.
