Telemarketer tarpit

Tarpiting is now a bit out fashioned when it comes to bulk mail, but it's extremely efficient against telemarketers. If you just hang up, they'll call the next person ten seconds later, but if you accept the call, pretent some ethusiam about the issue and tell them to wait a few seconds "so that you can take your cooking noodles off the stove"; leave the phone aside and continue your work they'll be bound for 4-5 minutes until they hang up for themselves. Well, except yesterday's moron from the "South German lottery" that needed 13:12 minutes until he realized I wouldn't come back...
