I don't remember where I saw this but it went something like:
".....No, I'm not interested in your special offer but if I am, I will call you back on your home phone to let you know. So just give me your home number and I will call you back......................................................Oh, why not? Why can't I call you on your home phone later tonight?....................What, you don't like people calling you on your home phone? Well, then why the FUCK are you calling on my home phone about this!?" *slam*
Thought it was brilliant.
