i did that when i was a kid. some guy was trying to sell us something and i picked up and then heard his thing and was talking then i hung up. well he called back and left a message on the machine saying "you should beat you kids ass". lmaotelemarketers....sometimes when I have nothing better to do I let them do their whole 2 minute speal and then I'll act interested and have them tell me more about what they are trying to sell and then I say yup thanks for telling me all that and click I hang up...the rest of the time I go postal on them and make them hang up on me
