Profitable, commendable, and a fine example to us all, but BORING!!!!!<p>Before I go on, yes, I do have way too much time on my hands, and a hugely immature area in my brain.<p>I like to go for creative abuse. Immediately I start arguing and generally giving them a hard time, winding up to virtual verbal abuse until....<p>...two things happen. They hang up, and never call back. Bonus: I feel better for getting some stuff off my chest. Dirt cheap therapy which they pay for!!!! Triple win. Yay!!!!<p>Dunno what its like in the US but here in the UK it seems that these people are not allowed to hang up. Big no no, from what I can tell. So, a great game is to time how quickly you can get them to hang up, or how long they can last out.<p>Should I grow up and generally get some sort of life? Yeah, probably.
