Charlie Sheen finally has his kids for a weekend, and he's expanding their vocabulary while he can.

LOS ANGELES, CALIFORNIA, UNITED STATES. HOLLYWOODTV - his weekend is the first time Charlie Sheen has been able to spend a weekend with Bob and Max since the judge took custody away from him in March and awarded it to their mother, Brooke Mueller. Charlie isn't wasting his time with the boys. Now that they're learning to speak, Charlie is teaching them new words this weekend.....words like "rehab". Charlie says it would be good to know the word, so they know where their mother spends all her time. Brooke Mueller recently failed a drug test, but remains in custody of the two boys, much to the dismay of Charlie Sheen. This is one case Charlie currently isn't 'winning'.
