Fun things to do to a telemarketer... I'll start off with a few. ^_^
1. Say "AT&T, how may I help you?". The telemarketer has a GOOD chance of being with AT&T (and it makes for one hilarious arguement)
2. start speaking in another language (or make up one if you don't know any)
3. Ask then, hypothetically, what they'd do if you just happened to be on the Do Not Call list. (they usually hang up PRETTY darn fast)
4. convince them that your crazy (like ask if the angels talk to them as well.)
Anyone else have any good ones?
