How to Annoy Telemarketers

Note: this is an unofficial guide to annoying the stupid people who get paid to drone on and on about a stupid company. This includes several different methods to annoying these seemingly idiotic people who practice this barbaric ritual that no one needs.
Steps
1. Talk like Dr. Phil, the psychologist. Pretend you know exactly what their problems are and convince them that they're possessed.
2. When they ask for a phone number, give Pizza Hut's phone number.
3. Talk like Yoda the entire time. Say things like "Idiot you are, imbecile."
4. Talk like famous celebrities, like George Bush or Arnold Schwarzenegger.
5. Mimic them like a parrot; when they ask you to stop, say "I'm the customer, dammit".
6. Talk as if you have something important to do all the time. Don't hang up.
7. Put them on hold for at least three minutes, then hang up.
8. Pretend you are cheating on your girlfriend while you're on the phone.
9. Wait and don't say anything. Go to the nearest computer and become mezmerized by the screen saver.
10. Act like a priest
11. Ask them for their home phone number. When they say no say "Oh, you don't want annoying people calling you at home. WELL NEITHER DO I!!!".
12. Fake a selection of noises in the background (gunshots).
13. Try and sell them something.
14. Laugh like a maniac every so often.
15. Sing loudly.
16. Blow down the phone.
17. If they are selling a "friends and family" package, tell them "I have no friends. will you be my friend?".
18. If possible, play the crazy frog tune down the phone. Full volume.
19. When asked if you want to buy something, just say "ok, but make it quick. I've got two dead people in the basement and a third with a knife through the ear".
20. Interrupt them with pointless questions.
21. Fake remembering them (e.g. Mark? Is that you? oh, hey, it's me, John. Remember me? From bedwetters camp? Oh, I've been trying to contact you for aaages. How's it hanging?"
22. Make it sound as though you are currently on the toilet.
23. make it sound as though you are a criminal. (e.g. Oh g-d, it's the cops. Look, I don't know how six tonnes of marajuana and two crates of illegal firearms got into my backyard. It just did, ok! I'll take it to you, but remember- the mob are gonna kill me, and possibly you for this.
24. State very scary "facts" (e.g. Did you know that twelve percent of murder victims are telemarketers?).

Tips
* You can simply ask them to put you on the no-call list; if they call you ever again, they are breaking the law.
* You can just hang up the phone the moment you know who it is!!

Warnings
* Remember that some of these people, are putting themselves through college, or might be supporting a family. They are only doing their job, and some people buy what they are selling, so its not a good idea to be disrespectful to them. When they call, its best to just hang up!
* Be cautious of what you actually say.
