Charlie Sheen and Brooke Mueller have made a special deal with their custody settlement.  The two re-hab veterans have agreed to no drug testing for either of them.  All I can think of is, "only in California".  Not trying to bag on either of them but they both have had quite a few past issues with drug abuse. They are parents of twin boys and have agreed to joint custody, no pun intended! Apparently, Brooke is still doing frequent trips to rehab and when that happens, the kids stay with her parents.  I don't know if I would want either of them watching my kids.]
