Maybe it's too early in the morning, but I don't get it

.
I do all sorts of stuff, but it's rare that I even answer the phone. My wife usually answers and she's not so good at hanging up, so I'll just unplug the phone from the wall to make it easier for everyone.
On the rare occassion I get roped in by a sales call, I'll do any number of the following:
1. Ask them to hold on and then place the phone down and walk away. This is my favorite. It requires minimal effort on my part AND it inconveniences the bastard who called me at dinner just as much as he inconvenienced me.
2. If I'm in a real bad mood and I'm feeling spiteful, I'll let them go through everything, I'll ask a bunch of questions, think about it, ask some more questions, and then say "thanks for calling bye" and just hang up. It REALLY wastes their time, but it also requires you to waste a fair amount of your own.
3. Another favorite of mine is to ask the caller for their name and number. Quite frankly, I think it's only fair that if they have YOUR information and can contact YOU at will, we should be able to do the same. If they won't give me their personal information, I just hang up. This is a real quick and easy way to make a very obvious point.
4. What usually happens, more than the others, is "You know it's fscking dinner time don't you? Don't ever fscking call here again." This one is more of a kneejerk reaction on my part than a conscious decision to screw with the chump on the phone.
MARKETING ONLY
Most telemarketing calls that we receive are companies doing marketing research. I despise these more than all the others because they offer no end-service to me whatsoever. At least the window fscker has something to sell me.
Ass: "Hi, we're conducting a survey on what America's favorite hobbies are and were wondering if you had somewhere between 5 and 1290384 minutes to spare?"
Me: "What's your rate?"
Ass: "Our rate? What do you mean?"
Me: "What will you be paying me to help your company do research?"
Ass: "Excuse me?"
Me: "I just worked 8 hours at a REAL job and I get paid for my time. If you want me to work for your company over the next 5 to 1290384 minutes, you're going to fscking pay me for it."
Ass: "!@#$ you <click>"
Me: "Ahhh... another satisfied client."
I really hate these research firms that call you up at 6:30 Monday evening for "5 minutes" of your time - which really means 45 minutes AT LEAST - and expect you to practically work in their marketing department for free. Fsck that.
