Missed Hit

Coworker: I have funny one today.
Me: Oh?
Coworker: I try to contact old tech who work at firm I was boss for.  I tell her I get Chinese mafia on her if she fail as a joke.  She say she have hard time at work on Facebook.  I call her and say “Chinese mafia going to kill you, ha ha ha”.  She scream and hang up.  Turns out, I have wrong number.
