Would you like to know why?
Massive stupidity.
Dude #1 puts a microphone up for sale on Craigslist.
Dude #2 stops by to check out the merchandise. Asks if he can take it outside and show it to his girlfriend.
Dude #1
Dude #2 prepares to make tracks.
Dude #1 runs outside with a handgun and starts shooting at the rapidly retreating car of Dude #2, then gets in his own idiot-mobile and starts chasing after his beloved microphone.
I like to think Dude #1 was screaming, "Momma there goes that man" as he gave hot and lethally intended pursuit to the miscreant.
Hat tip to D. Boren and RK Gaddie.
