no the best way is is this......
Awnser the phone and when they tell u what there selling be like "sure, ill buy w/e u got, but u have to send it to my new adress. The Wardens office,Maximum security wing, Attica pennetentiary, Attica NY"
OR
when they call be like "this nice officer next to me has advised me to tell u that this call is being monitered. now what drugs did u say u were selling?"
they wont call for a while after that
