This was told by a friend from Karachi, so can't guarantee the authenticity myself, but its interesting nevertheless.
So this friend says he stopped to buy groceries at a store and when he came out, a guy came up to him and said
''bhai, apka mobile gir gaya hai''.
Out of reflexes he reached to his pocket and felt for it, and replied ''nahi bhai, mera to meri jaib main hai" to which the guy replied showing a gun
"tau nikal do na bhai, kitna intizar karwao ge"
