i just think of the scene from boiler room... the guy trying to sell newspaper subscriptions....pretty funny.
What you do is when they ask for you " Say this is his brother, He died 6 months ago in a fatal car wreck,,, then go on to cuss them out for not having any respect and tell them that your going to sue their asses for unethical business practices, etc etc etc,," They will stop calling guaranteed, I used to have timeshare places calling me and since telling them i was dead, they never have called my number since, I to this day get 0 telemarketers calling me,,lol
