That didn't last long -- about two weeks after getting out of jail, Chief Keef is headed back.

According to TMZ, Keef failed a random drug test -- part of his probation for his arrest for doing 110 miles per hour in May. So a Chicago judge is sending him to a prison rehab center for 90 days

Even dumber -- Keef proudly tweeted the news, writing, "Judge putting me back in jail. See y'all later."

The Angles:

  • It's really not possible for this kid to get any dumber. He thinks this is all some kind of joke.
  • Maybe he figures he can avoid paying child support if he's locked up.
  • You could say this kid is the next Soulja Boy-type joke, but you'd be insulting Soulja Boy.
